The only brass hose-end available with the correct 18 seat for Stromberginlet fittings (original or S-jet). So no leaks and period looks too. Big 9/16″ AFhex cost us more to make but looks right on the hose. Perfect for 5/16″ ID hose- but 3/8″ ID hose also clamps up great.Note: This item is ineligible for return or exchange.
