About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Low-Pressure Steel Threaded Pipe Flanges

These flanges are for low-pressure applications in noncorrosive environments.

Low-Pressure Steel Threaded Pipe
Flanges for Low Temperatures

Use these Pressure Class 150 pipe flanges in low-pressure lines where temperatures drop down to -40° F.

Low-Pressure Galvanized
Steel Threaded Pipe Flanges

The galvanized finish on these Pressure Class 150 flanges provides fair corrosion resistance.

Low-Pressure Steel Unthreaded Pipe Flanges

Bolt two flanges of the same size together with a gasket to create an access point in a pipe line.

Low-Pressure Steel Unthreaded
Pipe Flanges for Low Temperatures

Even in temperatures as low as -46°, these A350 LF2 steel flanges won’t become brittle, so they absorb impact better than other low-pressure steel flanges.

Low-Pressure Stainless Steel
Unthreaded Pipe Flanges

Bolt two same-size flanges together with a gasket to create an access point within a pipe line.

Low-Pressure Stainless Steel
Threaded Pipe Flanges

Also known as Pressure Class 150 flanges, these corrosion-resistant flanges are designed for low-pressure pipe applications.

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.
