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.

Butt-Weld Fittings for Stainless Steel Tubing

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Extra-High-Polish Metal
Quick-Clamp Sanitary Tube Fittings

Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth.

High-Polish Metal Quick-Clamp
Sanitary Tube Fittings

The smooth finish inside these stainless steel quick-clamp fittings makes it easy to remove product residue.

Yor-Lok Fittings for Stainless Steel Tubing

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Metal Pipe and Pipe Fittings

Standard-Wall Butt-Weld Steel
Unthreaded Pipe Fittings

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Thick-Wall Butt-Weld Steel Unthreaded Pipe Fittings

With thicker, stronger walls than our standard-wall butt-weld pipe fittings, these fittings stand up to your high strength applications.

High-Pressure Socket-Connect
Steel Unthreaded Pipe Fittings

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

Thin-Wall Butt-Weld Stainless
Steel Unthreaded Pipe Fittings

Also known as Schedule 10 fittings, these are thin, lightweight, and corrosion resistant.

Standard-Wall Butt-Weld Stainless
Steel Unthreaded Pipe Fittings

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Thick-Wall Butt-Weld Stainless
Steel Unthreaded Pipe Fittings

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

High-Pressure Socket-Connect
Stainless Steel Unthreaded Pipe Fittings

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

Standard-Wall Butt-Weld Aluminum
Unthreaded Pipe Fittings

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings.

Thick-Wall Butt-Weld Aluminum
Unthreaded Pipe Fittings

Thick walls give these Schedule 80 fittings excellent strength.

Thin-Wall Butt-Weld Aluminum
Unthreaded Pipe Fittings

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Copper-Nickel Butt-Weld Pipe Fittings

Also known as Pressure Class 200 fittings.
