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 Brass and
Bronze Threaded Pipe Flanges

Also known as Pressure Class 150 flanges, these brass flanges are designed for low-pressure applications.

Low-Pressure Brass and
Bronze Threaded Pipe Fittings

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

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.

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.

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.

Expansion Joints with Flanged
Ends for Drinking Water

The EPDM lining in these joints meets NSF/ANSI 61 standard for use with drinking water.

Solder-Connect Fittings for Copper Tubing

Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

Press-Connect Fittings for Copper Tubing

Crimp these fittings to copper tubing with a crimping tool for a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings.

Water- and Steam-Resistant Pipe Gaskets with Bolt Holes

Water- and Steam-Resistant EPDM Pipe
Gaskets with Bolt Holes for Dissimilar Metals

Furnished with plastic sleeves and washers to provide a layer of protection against dielectric corrosion, which occurs when different metals are joined.

Water-Resistant Aramid/SBR Pipe Gaskets
with Bolt Holes for Uneven Surfaces

Often called controlled swell gaskets, these gaskets absorb water near the inside of the flange and swell to fill gaps. Use them on uneven surfaces, such as grooved, corroded, or pitted flanges.
