Air Compressor Fittings & Connectors
Connecting an air compressor to a tool sounds simple until you're standing in front of a wall of fittings trying to figure out what threads where. Most U.S.-market compressors and pneumatic tools use 1/4 inch NPT (National Pipe Tapered) thread — every fitting we stock is 1/4 inch NPT, and every threaded joint should be sealed with Teflon tape.
What fittings do you need?
A complete hookup needs five fitting types: a male NPT plug at the compressor outlet, a female quick-connect coupler on the air line, matching male plugs on the tool ends, a swivel connector to prevent hose kinking at the tool, and Teflon tape on every threaded joint. Browse individual pieces below, or grab everything in one package with the Air Compressor Hookup Kit.
