Quick Connect Hose Coupling: 1/4 in Body Size, 1/4 in Hose Fitting Size, Sleeve, Plug

Industrial interchange brass quick-connect air coupling plugs are the male end of coupling sets. Also called nipples, they're inserted into the coupling bodies (female ends) to connect tools to air, water, or fluid lines. High-flow couplings increase flow for greater tool efficiency, reduce pressure drop, and decrease air costs. Brass is a strong, highly conductive metal that resists corrosion and maintains durability at high temperatures. Brass is softer than other metal plugs and sockets for better connections and compatibility with copper or zinc piping.
