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.

Precision Extreme-Pressure Stainless Steel Threaded Pipe Fittings

Made to tighter tolerances than other stainless steel pipe fittings, these are also known as instrumentation fittings. The male threads are rolled for extra strength in extreme-pressure applications. Fittings are commonly used to connect equipment in gas and hydraulic fluid lines. They are 316 stainless steel for excellent corrosion resistance. Inline tees are also known as branch tees. Right-angle tees are also known as run tees.

Precision Extreme-Pressure Brass Threaded Pipe Fittings

Also known as instrumentation fittings, these have the most precise threads and the tightest tolerances of all the brass pipe fittings we offer. Fittings are brass for good corrosion resistance.

Inline tees are also known as branch tees. Right-angle tees are also known as run tees.

Push-to-Connect Fittings for Plastic Tubing—High-Purity

For Use With: Air, Nitrogen, Water
Temperature Range: 32° to 100° F
Tubing: Use with polypropylene plastic

Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings are produced in a clean room and are double bagged to prevent dirt and moisture from contaminating the inside. They are polypropylene, which has excellent impact and abrasion resistance.
