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.

Standard-Wall Aluminum
Threaded Pipe Nipples and Pipe

Typically used with low-pressure aluminum threaded pipe fittings.

Low-Pressure Aluminum Threaded Pipe Fittings

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

Thick-Wall Aluminum Threaded
Pipe Nipples and Pipe

Typically used with high-pressure aluminum threaded pipe fittings.

High-Pressure Aluminum Threaded Pipe Fittings

Also known as Pressure Class 3000 fittings, these have the highest pressure rating of all the aluminum pipe fittings we offer.

Medium-Pressure Aluminum Threaded Pipe Fittings

Designed for medium-pressure applications, these fittings have better strength than our low-pressure aluminum pipe fittings.

Miniature Medium-Pressure
Aluminum Threaded Pipe Fittings

Their small size makes these miniature fittings a good choice for cramped, confined spaces.

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.
