Marshall Excelsior Company

Marshall Excelsior builds the propane plumbing that connects RV tanks to appliances: regulators, pigtail hoses, and the adapters and fittings that tie the system together. The line runs deep on the connection details, with POL and QCC ends, quick-disconnects, inverted-flare and NPT adapters, fill valves, and high-flow LP hoses that you match by thread and pressure rating when servicing a gas system.
