A dependable, code-compliant propane connection for RV appliances, generators, grills, and high-demand regulator installations. This 30-inch Marshall Excelsior hose delivers the flexibility and pressure rating required for high-pressure LP systems, backed by fully crimped brass ferrules and a limited 5-year manufacturer warranty.
The Marshall Excelsior MER610-30 is a 30-inch flexible propane hose built for high-pressure applications -- connecting regulators, appliances, generators, or external propane sources where a rigid pipe connection is impractical or impossible. The 3/8-inch inside diameter core moves adequate propane volume for most RV appliance and generator demands, and the 350 PSIG working pressure rating gives a substantial safety margin above typical LP system pressures.
Both ends are terminated with industry-standard fittings: a 3/8" male NPT (pipe thread) on one end for threaded ports on regulators, manifolds, or appliance inlets, and a 3/8" female flare swivel on the other for standard flare connections. The swivel fitting allows you to tighten the connection without twisting the hose body, making installation significantly easier in tight compartments.
Fully crimped brass end fittings create a permanent, leak-resistant seal -- no clamps, no hose barbs to work loose over time.
Hose construction includes thermal protection to resist damage from ambient heat, a critical feature in enclosed RV propane compartments.
The 3/8" female flare swivel rotates independently of the hose body, preventing kinking and making single-person installation easier.
400-pound pull test rating confirms the end fittings won't separate from the hose under mechanical stress or vibration.
The 3/8" MNPT end threads directly into any standard female NPT port on a propane regulator, manifold, or appliance stub-out. The 3/8" female flare swivel accepts the standard 3/8" male flare fitting common on LP regulators, appliance supply lines, and distribution manifolds. Both connections are among the most common in RV and residential LP plumbing, so this hose works without adapters in the vast majority of installations.
This hose carries both UL (Underwriters Laboratories) listing and CGA (Canadian Gas Association) approval, meeting the safety and performance standards required for propane service in recreational vehicles and outdoor equipment. These certifications are required by many campground and RV park regulations and by NFPA 58 (LP-Gas Code) for compliant installations.
