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
Unthreaded Pipe Flanges

Use these heavy duty forged flanges for high-pressure applications.

High-Pressure Stainless
Steel Threaded Pipe Flanges

Also known as ANSI flanges.

High-Pressure Steel Unthreaded Pipe Flanges

Forged for extra strength, these heavy duty unthreaded flanges can withstand high-pressure applications.

Medium-Pressure Steel Threaded Pipe Flanges

With better strength than our low-pressure steel flanges, these are for use in medium-pressure applications.

Medium-Pressure Galvanized
Steel Threaded Pipe Flanges

Also known as Pressure Class 300 flanges, these medium-pressure flanges have a galvanized finish for fair corrosion resistance.

Flow-Control Flange Unions

Measure, throttle, and regulate the flow of liquids and gases in your line by adding an orifice plate to these unions.
