JR Products 07-31675 -- OEM 40" LP Supply Hose, 3/8" Diameter
A direct-fit OEM replacement LP supply hose for RV propane systems. Thermoplastic construction, 40-inch length, and 3/8" diameter for code-compliant gas delivery between regulators, manifolds, and fixed LP components.
The JR Products 07-31675 is a 40-inch OEM-specification LP supply hose engineered for use in RV propane gas distribution systems. Whether you are replacing a cracked, kinked, or age-degraded hose between a two-stage regulator and a distribution manifold, or reconnecting a fixed LP appliance feed line, this hose restores original system routing and flow capacity without modification.
At 3/8" inside diameter and 40 inches in length, this hose matches the internal routing dimensions used by many Class A, Class C, fifth-wheel, and travel trailer manufacturers who sourced LP plumbing components from JR Products. Thermoplastic construction resists cracking, UV degradation, and the repeated flexing common in slide-out or underbelly installations.
Matches factory routing and connection dimensions used by JR Products-supplied LP systems in many production RVs.
Flexible yet durable thermoplastic resists cracking, UV exposure, and repeated flex cycles in underbelly and slide-out installations.
Standard 3/8" LP hose diameter supports adequate propane flow for distribution manifold and regulator outlet applications.
40-inch length accommodates common factory routing paths without splicing or extending -- a direct swap for the OEM hose.
The 07-31675 is designed as a plug-in OEM replacement. If your existing hose is 40 inches and 3/8" diameter, this hose restores factory configuration without adapters or rerouting. Verify your existing hose end fittings and connection type before ordering to confirm compatibility.
This listing covers the hose assembly (part 07-31675). Confirm that the fitting type and thread size on both ends of your existing hose match this OEM replacement before installation. LP fittings are not universal -- incorrect connections are a safety hazard. If your system uses a different hose length, JR Products offers additional LP supply hose lengths in the same OEM series.
