JR ProductsUL/CSA ApprovedOEM ReplacementJR Products 07-31475 -- 60" OEM LP Supply Hose, 3/8" ID

A direct OEM-style replacement propane supply hose for RV appliances and coach LP systems. At 60 inches long with a 3/8" inner diameter rubber construction, this hose bridges your propane regulator or manifold to downstream appliances with properly sized, code-approved fittings on both ends. UL and CSA listed for peace of mind on gas-line repairs and upgrades.

The Right Hose for RV LP Supply Lines

Propane supply hoses in RVs take a beating -- heat cycling, vibration, ozone exposure, and years of coach flex work against the rubber over time. When a hose shows cracking, stiffness, or any sign of permeation, replacement is not optional. JR Products engineered this hose as a true OEM-grade option: the correct 3/8" ID bore maintains proper flow capacity for typical RV appliances, and the factory end fittings eliminate the need for adapters in most direct-replacement applications.

The 60" (5-foot) length provides enough slack to route cleanly from a through-the-floor or through-the-wall LP stub to a range, furnace, water heater, or other appliance -- while still leaving a service loop to absorb coach flex. Both ends are pre-installed and ready to wrench tight with standard tools.

OEM-Grade Construction

3/8" ID rubber hose built to original equipment standards, rated for LP (liquefied petroleum) gas service in RV and manufactured housing applications.

Ready-to-Connect Ends

1/2" female SAE flare fitting on one end connects to regulators, manifolds, and appliance inlets. 3/8" male pipe (NPT) on the other end threads directly into standard LP appliance ports.

UL and CSA Listed

Meets Underwriters Laboratories and Canadian Standards Association requirements for LP gas supply hose -- accepted by most RV service facilities and code inspectors.

Generous 60" Length

Five full feet of hose accommodates most under-floor and interior routing paths without splices or extensions, and leaves a service loop to prevent stress at fittings.

Fitting Compatibility

Understanding the two end fittings prevents mis-purchase:

  • 1/2" Female SAE Flare (large end): This is the standard POL-style female flare used on LP regulators, distribution manifolds, and the supply side of many RV appliance valves. It seats against a 45-degree male flare seat and tightens with a 1" wrench.
  • 3/8" Male NPT (small end): National Pipe Thread (tapered) -- threads directly into female NPT ports on furnaces, water heaters, ranges, and LP flex connectors. Use approved gas-rated thread sealant or PTFE tape rated for LP on this connection.
This hose is pre-assembled with both fittings installed -- no flaring tools or compression work required. Hand-start threads carefully, then tighten to snug with a wrench. Over-tightening NPT fittings can crack brass ports on appliances.

Typical RV Applications

This hose is commonly used as a supply line for:

  • Suburban and Atwood (Dometic) LP furnaces
  • Suburban and Atwood LP water heaters
  • RV range/cooktop supply connections
  • Propane distribution manifold outlet connections
  • Replacement of cracked or hardened OEM coach hoses during service or remodel
If your existing hose has different end fittings or a different length, JR Products offers multiple LP hose configurations. Verify both end fitting types and overall hose length before ordering to ensure a direct swap.

Installation Notes

Replacing an LP supply hose is a straightforward job for a competent DIYer, but propane work carries real risk. Follow these practices:

  • Turn off the propane supply at the tank valve completely before disconnecting any hose.
  • Use an approved gas-rated thread sealant (not standard white plumber's tape) on the 3/8" NPT male end.
  • The 1/2" SAE flare connection is a metal-to-metal seat -- no sealant is used on flare connections; rely on proper torque.
  • After installation, pressurize the system and leak-test every joint with an approved leak detection solution or calibrated detector. Never use an open flame.
  • Inspect the hose routing to ensure no contact with sharp edges, exhaust components, or areas with sustained high heat.
Propane hoses should be visually inspected at least once per season for cracking, abrasion, softening, or any odor of LP gas near the line. A hose showing any of these signs should be replaced immediately, regardless of age.

Important Information
  • This hose is rated for LP (propane) gas service only -- do not use with natural gas, compressed air, or any other media.
  • Always shut off propane at the tank before disconnecting or installing any LP hose.
  • Leak-test all connections with an approved detection solution after installation -- never use an open flame to check for leaks.
  • Do not kink, stretch, or route this hose against hot surfaces, sharp edges, or moving parts.
  • 90-day limited warranty covers manufacturer defects. Damage from improper installation or use voids coverage.
  • LP gas work may be subject to local code requirements. Verify applicable regulations before performing your own repairs.
