Quick Connect Hose Coupling, Global Style High Flow, Aluminum, Plug

Global-style high-flow aluminum 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. Aluminum couplings are lightweight and resist corrosion, but are more susceptible to scratches and wear unless alloyed with other metals for strength.
