How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

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, Female Quick Connect

For Use With: Air, Coolant, Nitrogen, Oil
Temperature Range: 0° to 210° F
Specifications Met: ASME B31.1, ASME B31.3, ASME B31.9
Pipe Nipples and Pipe: Use Quick-Disconnect Aluminum

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.

Quick-Connect High-Vacuum Fittings for Stainless Steel Tubing

Twist these fittings onto high-vacuum tubing to quickly make sealed, high-vacuum connections without the need for clamping, welding, or tools. To connect, insert your tubing into the fitting and twist the collar on the end of the fitting; an O-ring on the inside of the fitting compresses to form the seal. Also known as quick-disconnects, they're as easy to twist off as they are to twist on. Not for use in pressure applications.

Plugs fit inside the end of a quick-connect fitting to block it off when not in use.
