Running a larger propane appliance means the connecting hose needs to keep up with demand without becoming a weak link in the system. The Marshall Excelsior MER426H-15 is a Type 1 high-flow pigtail rated for up to 400,000 BTU, built with a 1/4" ID thermoplastic hose between a female QCC fitting and a 1/4" male NPT connection.
An excess-flow safety shut-off is built into the fitting, so the hose automatically restricts flow if it detects a sudden surge — a useful safeguard for any propane connection.
A solid choice when you're plumbing a higher-demand propane appliance and want a hose built to handle the flow safely.
