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 AN 37° Flared Fittings
for Stainless Steel Tubing

The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings.

Sleeves for Precision AN 37° Flared
Fittings for Stainless Steel Tubing

37° Flared Fittings for Copper Tubing

Also known as JIC (Joint Industrial Council) fittings, these connect to tubing that is flared to 37°. They can handle higher pressures than 45° flared fittings.

Nuts for 37° Flared Fittings for Copper Tubing

Sleeves for 37° Flared Fittings for Copper Tubing

Grip-Lock Hose Couplings for Air

These couplings have a lower profile than other claw-style couplings to fit in cramped spaces. They consist of a plug and a socket that connect with a quarter twist. Also known as Bowes couplings.

Snap-Tite H-Shape Quick-Disconnect
Hose Couplings for Hydraulic Fluid

Use these couplings at pressures up to 6,500 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with Snap-Tite H-Shape plugs and sockets.

Brazing Rings for Brass and Bronze
Unthreaded Pipe and Pipe Fittings

Snap one of these rings into an unthreaded pipe fitting and braze to unthreaded pipe for an extra-strong, leak-resistant connection.

Compact Pressure-Relief Valves

Less than a quarter of the height of standard pressure-relief valves, these are often installed on tanks in low-clearance areas.
