A fill valve that flows well matters when you're topping off a propane tank at the pump, and this ME601-6 valve from Marshall Excelsior is built for above-average flow rates at common fill pressures. The 1.75" Acme by 0.75" MNPT connection matches standard RV propane fill fittings.
It also includes a built-in breakaway feature: if a delivery hose gets pulled away during filling, the primary check valve stays intact instead of letting propane escape from the tank side.
A solid replacement fill valve for anyone whose current valve is worn, leaking, or filling too slowly.
