Speedaire Quick Connect Hose Coupling 1/4 in Body 30E657

Industrial interchange steel 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. Steel couplings are hard and resilient with more damage resistance than softer metals and a wide working temperature range.
