Built for lasting durability, the STEELMAN 60129 Dual Foot Closed Style 1/4-Inch FPT Air Chuck will always be ready for heavy-duty use. Made with a durable chrome-plated brass body tube and rust resistant zinc alloy head, this 6-inch long inflation tool has a double connector design that allows it to easily access standard valve stems as well as recessed stems and stems on inner rear tires on dualie / dual rear wheel type trucks and vehicles. The closed style chuck seals the air passage when it's not in use making it ideal for use on non-gauged tire inflators. The connection end is threaded 1/4-inch female NPT to easily fit male 1/4-inch NPT hose fittings and plugs. Perfect for commercial workshops and professional automotive mechanic use as well as in home garages.
