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.

Selecting Clamps Using Pipe, Conduit, or Tubing Trade Size

Low-Pressure Iron and Steel Threaded Pipe Fittings

Use these fittings for low-pressure applications in noncorrosive environments.

Saddle tap tees tap into existing pipe lines so you can install branch lines, valves, and other equipment. The gasket and clamps create a tight seal so the opening won’t leak. To install, shut down your line and secure the clamps, then drill a hole into the pipe.

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.

Snug-Hold Threaded-Rod-Mount Clamping Hangers

Load material between the two halves of the ring and adjust the side bolts for a tighter fit than standard threaded-rod-mount clamping hangers and loop hangers. All have a threaded hole on top for mounting with threaded rod.

Epoxy coated iron hangers are corrosion resistant and can be used with copper tubing.
