Tru-Flate automotive quick-connect air couplings are compatible with other Tru-Flate couplings of the same size regardless of pipe size or barbed hose ID. Also known as automotive or Milton T couplings, Tru-Flate couplings were originally designed for the automotive industry. Couplings have an integral sleeve guard to resist accidental disconnection and a tubular valve that delivers high air flow. High-flow couplings increase flow for greater tool efficiency, reduce pressure drop, and decrease air costs. These multipurpose couplings connect air tools and hoses to compressed air supplies for grease guns, drop-down air lines, and paint applicators.
