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-Polish Metal Quick-Clamp Sanitary Tube Fittings

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

Clamps for High-Polish Metal
Quick-Clamp Sanitary Tube Fittings

Connect quick-clamp sanitary tube fittings—also known as aseptic fittings—for a fast and easy way to access your line.

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

Also known as I-line fittings, these quick-clamp fittings permit easy access to your line.

Clamps for Extra-Support High-Polish
Metal Quick-Clamp Sanitary Tube Fittings

Connect extra-support quick-clamp fittings for a fast and easy way to access your line.

Plastic Quick-Clamp Sanitary
Fittings for Stainless Steel Tubing

Sanitary Sampling Stainless Steel Tube Fittings

Take samples in sanitary environments—these tube fittings won’t contaminate your lines or force you to pause them.

Pipe and Pipe Fittings

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.

CPVC Pipe Flanges for Hot Water

Bolt two same-size flanges together with a gasket to create an access point within a line. They are also known as Pressure Class 150 flanges. Use in high-temperature plumbing and water supply applications up to 200° F.

Drain, Waste, and Vent ABS
Pipe Flanges for Chemicals

Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges are an economical option for gravity-flow chemical waste systems. They are ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

Easy-Access CPVC Pipe Flanges for Chemicals

The grooved ends on these flanges connect to pipe with a clamp, so you can access your chemical process line for routine maintenance. Flanges have excellent chemical resistance to withstand a variety of salt solutions, acids, and other harsh substances. They are also known as Victaulic flanges.

Aboveground Standard-Wall PVC Pipe
Flanges for Drain, Waste, and Vent

Bolt two same-size flanges together with a gasket to create an access point within a line. Also known as Schedule 40 flanges, they are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.
