This hard spout is tough & built to last years. Multi-purpose, it can be used on gas, kerosene, diesel & water plastic cans. May also be compatible with some metal cans-those that use a standard spout like some Midwest & Briggs jerry cans. Special angle shape allows fluid to easily flow out without the mess. In the uncommon instance where our base cap does not fit the can, the factory cap may be used with our spout. Includes 1 spout, 1 spout cap, 2 base caps (fine & coarse), 1 gasket, 1 filter screen (flame arrestor) & 1 push-in vent cap.
