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.

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.

Extreme-Pressure Steel Unthreaded Pipe Flanges

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

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.

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.

High-Pressure Steel Threaded Pipe Flanges

Also known as Pressure Class 1500 steel flanges, these have the strength to handle high pressures.

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.

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.

High-Pressure Stainless
Steel Threaded Pipe Flanges

Also known as ANSI flanges.

Plastic Pipe and Pipe Fittings

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.

Thick-Wall Plastic Pipe Flanges for 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. They have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation.

UV-Resistant Polypropylene
Pipe Flanges for Chemicals

Use these polypropylene flanges in outdoor environments—they resist the damaging effects of ultraviolet light. They have the chemical resistance to stand up to acids, solvents, and other harsh substances. Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges are also known as Pressure Class 150 flanges.

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.

Flame-Retardant PVDF Pipe Flanges for Chemicals

Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges meet UL 94 V-0 for flame retardance to delay the spread of flames to valuable equipment. They are PVDF, which is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances. Also known as Pressure Class 150 flanges.

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.
