Aluminum Quick-Connect Pipe Fittings for Compressed Air
Twist these fittings onto aluminum pipe for quick, sealed connections—no threading, soldering, or welding necessary. Use them to build a compressed air system in half the time it would take to build a copper or steel system. Also known as Unipipe fittings, they’re part of a quick-connect system that’s compatible with pipe from Unipipe, Transair, and Infinity.
Finger tighten the collar on the end of these fittings, then use a wrench for the final quarter turn. The inside of these fittings has a compression ring and O-ring to seal against the pipe. They’re easy to take apart as needed to modify your setup.

Plugs block the end of a fitting. They include a ¼ BSPP valve that can be used to exhaust your line or attach a pressure gauge. To install, remove the fitting's nut, collar, and grip ring. Insert the plug into the fitting, slide the collar on, and tighten the nut. Discard the connector's grip ring.
