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.

High-Pressure Stainless Steel Threaded Pipe Fittings

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

High-Pressure Brass Threaded Pipe Fittings

These brass fittings have the strength to handle high-pressure applications.

High-Pressure Brass Threaded
Pipe Fittings with Sealant

Not only do these brass fittings have the strength to handle high-pressure applications, the male threads have a sealant applied for extra protection against leaks.

High-Pressure Brass Threaded
Pipe Fittings for Drinking Water

Use these heavy-duty brass fittings for high-pressure drinking water applications.
