About Pipe and Fittings

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

Metal Pipe and Pipe Fittings

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.

High-Pressure Steel Unthreaded Pipe Flanges

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

High-Pressure Steel Unthreaded SAE Pipe Flanges

Also known as Code 61 SAE hydraulic flanges.

Extreme-Pressure Steel Unthreaded Pipe Flanges

For excellent strength in extreme-pressure applications, choose these heavy duty Pressure Class 1500 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.

High-Pressure Stainless Steel
Unthreaded Pipe Flanges

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

High-Pressure Stainless Steel
Unthreaded SAE Pipe Flanges

Also known as Code 61 SAE hydraulic flanges.

High-Purity Polypropylene Pipe Flanges for Corrosive Chemicals

High-Purity Polypropylene Pipe
Flanges for Corrosive Chemicals

The inside of these flanges won’t leach contaminants into your line or accumulate particles—they’re polished to an ultra-smooth 12 Ra finish, which also makes them easy to clean. Made of polypropylene, they resist organic solvents, acids, and alkalis better than CPVC pipe flanges.
