JR Products UL/CSA Approved OEM Replacement JR Products 07-31445 -- 36" OEM LP Supply Hose

A direct OEM-style replacement propane supply hose for RV appliance connections. The 07-31445 delivers a reliable, code-compliant link between your LP regulator or manifold and downstream appliances -- with the right fittings already installed and safety approvals to match.

Reliable LP Plumbing With the Right Ends Already Installed

Sourcing a replacement propane hose with mismatched fittings is one of the most common RV repair headaches. JR Products eliminates that problem with the 07-31445: a 36-inch OEM-spec hose that ships with a 1/2" female SAE flare fitting on one end and a 3/8" male pipe (MPT) fitting on the other -- the two most common LP connection sizes found on RV appliances, regulators, and quick-connect manifolds.

The hose body is 3/8" ID rubber rated for LP gas service and approved by both UL and CSA, meeting the safety standards required for propane plumbing inside and outside recreational vehicles. It is an ideal drop-in replacement for worn, cracked, or leaking OEM hose runs on ranges, furnaces, water heaters, and other LP-fed appliances.

OEM-Matched Fittings

1/2" female SAE flare x 3/8" male pipe thread -- the two most common LP end types on RV appliances and regulators. No adapters needed in most installations.

LP-Rated Rubber Construction

3/8" ID rubber hose formulated for liquid propane and vapor service. Resists fuel permeation and maintains flexibility across typical RV operating temperatures.

UL and CSA Approved

Dual safety listing means this hose meets recognized North American standards for LP gas applications -- important for insurance compliance and campground inspections.

36" Working Length

Generous 36-inch length accommodates most under-range, under-counter, and compartment appliance runs without splicing or extending the original routing.

Common RV Applications

This hose is a frequent replacement item for:

  • RV range and cooktop LP supply lines
  • Furnace and wall-heater propane feeds
  • LP water heater inlet connections
  • Propane regulator outlet-to-manifold runs
  • Generator LP supply lines (where 3/8" ID is specified)
No Adapters Required for Standard Connections: The 1/2" female SAE end threads directly onto standard LP appliance inlets and regulator outlets. The 3/8" male pipe end connects to standard pipe-thread fittings on manifolds and appliance valves -- making this a true plug-and-play OEM replacement in most rigs.

Fitting and Thread Details

Understanding the two end types helps you confirm fitment before ordering:

  • 1/2" Female SAE Flare (POL-style): This is a left-hand-thread flare nut used throughout LP regulator and appliance connections. It seals on a metal-to-metal flare seat -- no tape or thread sealant is used on the flare face.
  • 3/8" Male Pipe Thread (MPT): Standard right-hand NPT pipe thread. Use yellow PTFE tape or an approved LP-rated pipe thread sealant on this end when connecting to female pipe fittings.
Thread Sealant Note: Apply yellow gas-rated PTFE tape or LP pipe dope only to the 3/8" MPT pipe end. Never apply sealant to the SAE flare fitting -- it seals on the flare seat, not the threads. Improper sealant application on flare fittings can prevent a proper metal-to-metal seal.

Installation Tips

  • Shut off the LP supply at the tank or main shutoff valve before beginning any hose replacement.
  • Route the hose away from heat sources, sharp edges, and moving components.
  • Do not exceed the hose's natural bend radius -- avoid kinking, which restricts flow and can damage the hose wall over time.
  • After installation, perform a leak test with approved LP leak detector solution before restoring gas supply.
  • Inspect the hose annually for cracking, abrasion, or softening of the rubber jacket.
Maintenance Tip: Propane hoses exposed to UV light, ozone, and temperature cycling have a finite service life. Even without visible damage, hoses older than 5-7 years should be inspected closely and replaced if any stiffness, surface cracking, or discoloration is found. The 07-31445 is an affordable preventive replacement.

  • Always shut off the LP supply at the tank before disconnecting or installing any gas hose.
  • Never apply PTFE tape or pipe sealant to the SAE flare fitting end -- it seals on the metal flare seat, not the threads.
  • Do not use if the hose is kinked, cut, abraded, or shows any signs of cracking or deterioration.
  • Always perform an LP leak test with approved detector solution after installation before lighting any appliance.
  • Installation must comply with applicable LP gas codes, NFPA 58, and any local regulations. If in doubt, consult a certified LP gas technician.
  • Limited 90-day manufacturer warranty. Warranty void if hose is modified, used outside rated service, or improperly installed.
