Dixon J3F3 Tru-Flate Automotive Quick Connect Plug, 3/8 in Body, 3/8 in FNPT, Zinc Plated Steel, 500 psi

Tru-Flate automotive steel 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.
