A purpose-built liquid propane gas hose for RV, camper, and outdoor LP applications. The MER613-30 connects two 3/8" female flare fittings with a flexible, thermoplastic body rated to 350 PSI working pressure -- giving you solid, tested performance for tank-to-regulator and regulator-to-appliance runs.
Marshall Excelsior has been manufacturing propane and LP gas handling equipment in the USA for decades. The MER613-30 is part of their proven hose line -- built to UL and CGA standards and assembled with fully crimped brass ferrules on both ends for leak-free, long-term performance in demanding RV environments.
At 30 inches in length with a 3/8" inside diameter, this hose gives you enough reach to make clean, low-stress connections between tanks, regulators, and downstream appliances without sharp bends or strain on fittings. The flexible thermoplastic construction resists cracking and kinking, even in cold weather conditions common during fall and winter camping.
Rated for 350 PSI working pressure with a 400 lb pull test -- exceeds typical RV LP system operating pressures by a wide margin.
3/8" female flare swivel on both ends allows easy connection and disconnection without twisting or stressing the hose body.
Certified to Underwriters Laboratories and Compressed Gas Association standards -- compliant for LP gas service on RVs and outdoor appliances.
Built-in thermal protection safeguards the hose from heat sources commonly found near RV LP systems and outdoor cooking setups.
The hose body is flexible thermoplastic rated for LP liquid and vapor gas service. Both ends are finished with fully crimped brass ferrules -- a more durable and leak-resistant termination method than screw-on or barbed fittings. The 3/8" female flare swivel connections follow standard CGA flare fitting dimensions and mate with the vast majority of LP regulators, POL adapters, and appliance inlets used in RV applications.
LP gas hoses should be inspected before each camping season and replaced if you find any of the following:
The MER613-30 carries a limited 5-year manufacturer warranty from Marshall Excelsior. It is manufactured in the USA -- a distinction that matters when you are relying on the hose in a safety-critical LP gas system.
