BK Resources Fryer Hose Kit for Natural Gas and Propane Deep Fryers

BK Resources Fryer Hose Kit for Natural Gas and Propane Deep Fryers (BKG-GHC-7548-SCK3, 3/4-Inch x 48-Inch, cCSAus Certified)

This BK Resources gas hose connection kit, sold as a complete commercial fryer gas hose assembly, is the 3/4 inch inner diameter, 48 inch long Kit #3 configuration built for natural gas and propane deep fryers, restaurant ranges, and any caster-mounted moveable commercial cooking equipment. As a deep fryer hose and a fryer gas hose in one bundle, it replaces the gas line for fryer hookups on rolling appliances without requiring a separate hardware run. The hose is heavy-duty welded stainless steel tubing protected by a radial-wrap stainless braid that prevents tube stretching every time the appliance is rolled out for cleaning. Over the braid is an antimicrobial PVC coating in a protective translucent finish that inhibits the growth of bacteria, mold, and mildew on the connector itself. The Kit #3 hardware bundle is the most complete configuration BK Resources offers and includes a shut-off ball valve, a quick disconnect, a restraining cable with full mounting hardware, two female-to-male 90 degree street elbows, 90 degree female elbows, threaded nipples, and the Swivel Pro stress-relief device on the hose ends.

As a deep fryer gas connection assembly, the kit is cCSAus certified and complies with ANSI Z21.69 / CSA 6.16 for connections to movable gas appliances. The optional quick connect complies with ANSI Z21.41 / CSA 6.9 for use with gas fuel appliances. Approvals on file include Z21.69, Z21.69b, Z21.69-2002, Z21.41-2003, Z21.41a-2005, and Z21.41b-2010. The hose is warranted for 5 years from the date of installation against defects in material and workmanship. All other kit components, including the shut-off ball valve, quick connect, restraining cable, and installation hardware, are warranted for 1 year. The kit ships in a point-of-purchase display box. Beware of look-alike gas connection kits sold at deep discounts, those bogus knock-offs are made with sub-par materials and inadequate quality control standards that can jeopardize the safety of the kitchen.

What Is Included in the BKG-GHC-7548-SCK3 Kit

• 3/4 inch I.D. x 48 inch heavy-duty welded stainless steel gas hose with radial-wrap stainless braid and antimicrobial translucent PVC coating
• Swivel Pro stress-relief device on the hose ends to reduce stress as equipment is moved
• Shut-off ball valve (manual gas shut-off)
• Quick disconnect coupler with sleeve and nipple
• Two female-to-male 90 degree street elbows
• 90 degree female elbows for offset positioning
• Threaded nipples for NPT connections
• Restraining cable with round-head bolt, washers, locking nuts, cable bracket, four wall screws, and plastic anchors
• Caster warning label for casters-equipped appliances
• Point-of-purchase display box packaging

Best Use Cases for This Gas Hose Connection Kit

• Caster-mounted commercial deep fryers that need to roll out from the line for cleaning
• Natural gas and propane fryer batteries on rolling stands
• Restaurant ranges, charbroilers, and griddles installed on caster bases
• Food truck and concession trailer kitchens with moveable gas appliances
• Tilt skillets and braising pans on caster bases
• Combi ovens and convection ovens on rolling stands that need to be pulled out for service
• Stationary gas appliances that still require flexible connection per local code
• Replacement of older gas connectors that have reached end of service life

Why Kit #3 Versus Kit #2 or Kit #9

BK Resources offers three gas hose connection kit packages. Kit #3 is the full-featured configuration and includes the shut-off ball valve, the quick disconnect, the restraining cable and hardware, both 90 degree street and 90 degree female elbows, threaded nipples, and the Swivel Pro stress-relief device. Kit #2 trims down the hardware bundle, and Kit #9 is a different configuration mix. Buyers who want the fastest disconnect-and-roll workflow with a single quick-release coupler should specify Kit #3. The two 90 degree elbows let the hose route around the appliance back panel and the gas supply stub-out without forcing sharp bends or kinks in the hose body itself.

Why a 3/4 Inch x 48 Inch Hose for Deep Fryers

The 3/4 inch inner diameter is the workhorse size for commercial deep fryers and most full-size gas appliances. At 48 inches of length, the hose has enough slack to allow the appliance to roll fully out from the wall for floor cleaning and behind-the-line service without pulling the connection taut. The 48 inch length is the most common stock length for fryer batteries and ranges in standard 24 to 36 inch deep cook lines. Shorter lengths (24 or 36 inch) are sized for tighter installs, and longer lengths (60 or 72 inch) are for appliances that need to roll farther from the wall.

BTU Capacity Charts

Capacity values are developed using ANSI Z21.69 specifications at 0.5 inch water column (124 Pa) pressure drop, 0.64 specific gravity, 1,000 BTU per cubic foot (37.2 MJ/m3) gas, straight length capacity in BTU per hour. The 3/4 inch x 48 inch hose values are the row that applies to this BKG-GHC-7548-SCK3 kit.

1 inch	377,000	373,000	368,000	344,000	339,000

For the 3/4 inch x 48 inch (4 foot) BKG-GHC-7548-SCK3 with full Kit #3 hardware (shut-off ball valve plus quick connect installed), the rated capacity is 184,000 BTU per hour at 0.5 inch water column pressure drop. The capacity at 0.2 inches water column (50 Pa) pressure can be determined by multiplying by 0.632. For capacities under conditions other than those noted, the manufacturer or serving gas supplier should be contacted.

Construction and Materials

The hose body is heavy-duty welded stainless steel tubing rather than corrugated brass or coated rubber. Welded stainless tubing handles repeated flex cycles from rolling caster appliances without fatigue cracking. The radial-wrap stainless braid over the tubing locks the tubing diameter in place, which prevents the tubing from stretching and thinning as the appliance is moved back and forth during cleaning. The Swivel Pro stress-relief device on each hose end further reduces the bending stress concentrated at the threaded connection points, which is the most common failure point on cheap gas connectors.

Over the stainless braid is an antimicrobial PVC coating in a protective translucent finish. The antimicrobial agent inhibits the growth of bacteria, mold, and mildew on the outer surface of the connector, which matters in fryer zones where airborne grease and humidity create ideal microbial growth conditions. The translucent finish lets the operator visually inspect the stainless braid through the coating during routine maintenance.

Installation Overview

All installation and testing must be performed by qualified personnel. Installation must comply with the National Fuel Gas Code (ANSI Z223.1, NFPA 54) or CSA B149.1 Natural Gas and Propane Installation Code as well as any local gas installation codes. The kit can be installed in two configurations depending on whether the optional quick connect is used.

Configuration 1: With Optional Quick Connect Device

• Shut-off ball valve installed at the gas supply side
• Female-to-male 90 degree elbow off the supply side ball valve
• Gas hose between supply and appliance sides
• Quick connect coupler at the appliance side with male nipple half on the appliance and female coupler on the hose
• Female-to-male 90 degree elbow at the appliance NPT stub-out
• Restraining cable kit installed and connected

Configuration 2: Without Quick Connect Device

• Shut-off ball valve installed at the gas supply side
• Female-to-male 90 degree elbows at both supply and appliance sides as needed for offset
• Gas hose threaded directly between the two 90 degree elbows
• Restraining cable kit installed and connected

Required Pre-Install Steps

• Shut off the main gas line and the connecting shut-off ball valve before any work begins
• Verify there is absolutely no gas flow before disconnecting or threading any fitting
• Select hose length to match the actual run between supply stub-out and appliance stub-out without slack pile-up
• Install the manual shut-off ball valve within 6 inches of the appliance gas connection point per code
• Verify the gas flow direction arrow on the quick connect matches the supply-to-appliance flow
• Use thread sealant or thread tape on every NPT connection
• Tighten all connections using wrenches
• Test the final assembly for leaks per ANSI Z223.1 / NFPA 54 or CSA B149.1 (no open flames, water rinse after test solution)

Restraining Cable Installation (Required for Warranty)

• The restraining cable MUST always remain installed and connected while the gas hose is in service
• Failure to install the restraining cable kit voids the gas hose warranty
• Attach the cable bracket to the wall using the four screws provided, hitting wood or metal studs where possible
• Use the supplied plastic anchors when no stud is available
• Drill the appliance carefully, verifying that the bit will not strike any internal operating parts as it passes through the metal exterior
• Install the round-head restraining bolt with washer through the appliance hole, secure with a second washer and locking nut
• Attach the restraining cable to both anchor points with the hooks snapped closed
• If the appliance is on casters, permanently attach the supplied caster warning label in a prominent position

Common Installation Mistakes to Avoid

• No sharp bends in the hose body, the radial-wrap stainless will not prevent kinking on a sharp angle
• No twists in the hose, twisting strains both the tubing and the threaded connection points
• No double bends (S-curves) along the run
• The hose must not touch the floor at any point along the run
• Do not bend or flex the hose at the threaded connection points themselves
• Do not strain the connections by forcing excessive bending or kinking during install
• Do not use the quick connect on dual-fed gas manifold line-ups, only the manual shut-off ball valve should be used in those applications because gas being fed from two locations prevents the quick connect's safety shut-off from working properly
• Do not use sources of ignition or open flames for leak testing
• Do not relocate an installed hose to another appliance, a new hose and supporting hardware must be used for each application
• Do not adjust or repair the quick connect, its moveable internal parts can be permanently damaged. If a problem occurs, shut off gas immediately and contact qualified personnel
• Do not use strong cleaning products on the connection points. Use mild cleaners and rinse with water immediately after cleaning

Disconnecting and Reconnecting for Cleaning

To Disconnect the Gas Hose

• Turn all gas supply and appliance knobs to the full OFF position
• Pull back the coupler on the quick connect to release the gas hose nipple from the sleeve
• Keep the gas hose and quick connect nipple clean, do not let either touch the floor
• After removing the hose from the appliance, the restraining cable may be disconnected

To Reconnect the Gas Hose

• Verify the safety shut-off ball valve and all appliance knobs remain in the OFF position
• Re-connect the restraining cable to its proper anchor points first
• Pull back the coupler on the quick connect to open the sleeve, then push the nipple into the female half
• Continue pushing the nipple into the sleeve until it clips into place
• Lightly pull on the hose to confirm the connection is secure, with no space between the sleeve and nipple
• Turn gas flow back on at the shut-off ball valve
• Always check for leaks when re-connecting the gas line

Beware of Counterfeit Gas Connection Kits

Look-alike gas connection kits are sold at deep discounts on online marketplaces and at low-tier supply outlets. These bogus knock-offs are made with sub-par stainless tubing, inferior PVC coatings, and inadequate quality control standards that can fail under normal commercial cooking conditions. A failed gas connection in a fryer zone can cause fire, explosion, or carbon monoxide release, all of which jeopardize the kitchen and the people working in it. Always verify cCSAus certification, ANSI Z21.69 compliance, and the BK Resources brand markings on both the hose body and the included hardware before installation. The point-of-purchase display box and the BK Resources hardware embossing on the swivel and quick connect bodies are quick visual checks during the unboxing.

Frequently Asked Questions

What is the difference between BKG-GHC-7548-SCK3 and CP-7548-SCK3?

The CP- prefix is a legacy BK Resources part number for the same 3/4 inch x 48 inch Kit #3 gas hose connection kit. Current production uses the BKG-GHC- prefix. Functionally identical kit, same components, same certifications, same warranty.

Will this kit work with both natural gas and propane fryers?

Yes. The hose, ball valve, and quick connect are approved for 1st, 2nd, and 3rd family gases under 50 mbar pressure, which covers both natural gas and propane (LP) at standard commercial appliance pressures.

What BTU rating does this kit support?

For the 3/4 inch x 48 inch hose with the full Kit #3 hardware installed (shut-off ball valve plus quick connect), the rated capacity is 184,000 BTU per hour at 0.5 inch water column pressure drop. With only the manual shut-off ball valve and no quick connect, capacity rises to 280,000 BTU per hour. With hose only, the minimum connector capacity is 215,000 BTU per hour.

Do I have to use the restraining cable?

Yes. The restraining cable is required by code for any flexible gas connection on a moveable appliance, and the BK Resources warranty is void if the restraining cable kit is not installed and used. The cable prevents the hose from being pulled past its safe travel limit, which protects against gas leaks if the appliance is rolled too far from the wall.

Does the quick connect work with dual-fed gas manifolds?

No. The optional quick connect is not for use with any dual-fed gas manifold line-up applications. Only the manual shut-off ball valve can be installed in dual-fed setups because gas being fed from two locations prevents the quick connect's safety shut-off from working properly.

How far does the manual shut-off ball valve have to be from the appliance?

The approved manual gas shut-off ball valve must be installed at the connection point from the gas line to the gas hose, and must be located within 6 inches of the appliance it is attached to.

Can I use this hose on stationary equipment?

Yes. The kit is built primarily for moveable equipment, but stationary commercial appliances often use a flexible gas connector for ease of service. For stationary appliances, avoid any unnecessary movement or vibration after installation. The hose is designed and intended for use with mobile gas equipment, but flexible connectors on stationary appliances are common and accepted under most local codes.

What gauge is the stainless steel hose?

The hose body is heavy-duty welded stainless steel tubing with a radial-wrap stainless steel braid over the tubing. The radial wrap prevents tube stretching as the equipment is moved. Specific gauge is not listed, the hose is rated by the BTU capacity charts above and by ANSI Z21.69 compliance.

What is the antimicrobial coating for?

The antimicrobial agent in the translucent PVC coating inhibits the growth of bacteria, mold, and mildew on the outer surface of the connector. This matters in fryer zones where airborne grease and humidity create ideal microbial growth conditions on exposed hose surfaces.

How often should the hose be replaced?

BK Resources warrants the hose for 5 years from the date of installation. Replacement timing depends on use intensity, exposure to grease and cleaning chemicals, and visual condition of the radial wrap and PVC coating. The hose should be replaced if any kinks, tube stretching, coating cracks, or visible braid damage are observed. The hose must not be relocated to a new appliance, a new hose and hardware must be used for each application.

What is the maximum operating temperature?

The hose should not contact anything over 110 degrees C (230 degrees F). Maintain clearance from radiant heat sources, hot exhaust ducts, and hot appliance surfaces during installation routing.

What size faucet pipe thread does the hose use?

The hose connections are NPT threaded. The kit includes 90 degree female elbows and 90 degree female-to-male street elbows to handle most standard fryer and range stub-out configurations. Apply thread sealant or thread tape on every NPT connection during install.

Can I install this myself?

No. Installation and testing must be performed by qualified personnel per ANSI Z223.1 / NFPA 54 or CSA B149.1. Improper installation of a gas connection can cause fire, explosion, or carbon monoxide release. The 5-year hose warranty also requires installation compliance with American Gas Association Standards or American National Standards.

Why are some gas hose kits sold at very low prices?

Counterfeit and look-alike gas connection kits are sold on online marketplaces and at low-tier supply outlets at deep discounts. These bogus knock-offs use sub-par materials and inadequate quality control standards that jeopardize kitchen safety. Always verify cCSAus certification, ANSI Z21.69 compliance, and BK Resources brand markings on both the hose and the hardware before installation.

Is this the same product as a deep fryer hose or a gas line for a fryer?

Yes. A deep fryer hose, a fryer gas hose, a gas hose for fryer, and a gas line for fryer all refer to the flexible gas connector that runs from the building gas stub-out to the back of the fryer. This BK Resources kit is the full deep fryer gas connection bundle, with the hose plus the shut-off valve, quick disconnect, and restraining cable required by code for moveable commercial cooking equipment.

What pressure can the quick connect handle?

The maximum fuel gas pressure to be used with the quick connect is 1/2 psi (3.5 kPa). The quick connect is approved for 1st, 2nd, and 3rd family gases under 50 mbar pressure.

Where do I send a warranty claim?

Return defective product with proof of purchase during the warranty period to BK Resources, 120 Frontage Rd, Altamont, IL 62411. Phone 888-310-4393.
