A reliable, code-compliant LP pigtail hose built for RV propane systems. This 15-inch hose connects a QCC Type 1 (Acme-style) tank fitting directly to a 1/4-inch male inverted flare regulator or manifold inlet -- the standard interface on most RV dual-stage and automatic changeover regulators. Rated to 350 PSIG working pressure and UL/CGA approved, it handles the demands of full-time RV use, boondocking, and seasonal camping.
The MECMER425-15 is manufactured by Marshall Excelsior, a U.S. propane component specialist whose pigtail hoses are widely used in RV OEM and aftermarket applications. The hose features a flexible thermoplastic construction with fully crimped brass ferrules on both ends -- no field-assembled fittings that can work loose over time.
At 15 inches, this is the standard pigtail length for connecting a 20 lb. or 30 lb. DOT cylinder to a side-by-side dual-bottle regulator bracket. It provides enough slack to allow cylinder removal and reinstallation without straining the regulator connection.
Rated 200,000 BTU/hr with 100 SCFH flow capacity. Supports full RV appliance loads including furnace, range, water heater, and generator simultaneously.
Built well beyond normal LP system operating pressures for a wide safety margin. Pairs with a 400 lb. pull test rating on the crimped brass ferrules.
Integrated thermal protection sleeve guards the hose from engine compartment and generator heat -- important for motorhomes and rigs with exposed propane runs.
Meets UL 21 and CGA standards for LP gas hose. Compliant for use in RV propane systems and accepted by most campground and safety inspections.
Getting the fittings right is critical on LP connections. This hose uses two distinct ends:
Confirm your regulator inlet accepts a 1/4-inch male inverted flare before ordering. Some regulators use a 3/8-inch inverted flare inlet -- those require the MECMER430 series instead.
