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 Clamp-On Connectors
for Drain, Waste, and Vent

To make installing and maintaining systems easy, these connectors come with clamps that form a strong seal on pipe and fittings once tightened.

Low-Pressure Clamp-On Connectors for Air

These connectors are for use in low-pressure air and vacuum conveying systems, as well as in gravity-flow systems.

Low-Pressure Quick-Lock
Clamp-On Connectors for Air

A turn of the T-handle will tighten and loosen these connectors, so you can quickly disassemble and reassemble your lines without tools.

Medium-Pressure Clamp-On Connectors

Use in medium-pressure applications up to 230 psi.

CPVC Pipe Fittings for Hot Water

Connect to CPVC pipe for use in high-temperature plumbing and water supply applications.

CPVC Pipe for Hot Water

Connect to CPVC pipe fittings for use in high-temperature plumbing and water supply applications up to 170° or 200° F.

Clamps for Easy-Access CPVC
Pipe Fittings for Chemicals

Use these clamps to connect easy-access CPVC pipe fittings and pipe.

Easy-Access CPVC Pipe for Chemicals

Also known as Victaulic pipe, this pipe has grooved ends that connect to fittings and flanges with a clamp, so you can access your line for routine maintenance. It is CPVC, which has excellent chemical resistance to withstand a variety of salt solutions, acids, and other harsh substances.

Easy-Access CPVC Pipe Fittings for Chemicals

Also known as Victaulic fittings, these have grooved ends that connect to pipe with a clamp, so you can access your chemical process line for routine maintenance. Fittings have excellent chemical resistance to withstand a variety of salt solutions, acids, and other harsh substances.

Gravity-Flow CPVC Pipe Fittings
for Corrosive Chemical Waste

These fittings are NSF certified for use in corrosive waste gravity-flow systems. Made of CPVC, they have better chemical resistance than ABS plastic gravity-flow fittings and can stand up to highly-corrosive acids and other harsh substances.

Gravity-Flow CPVC Pipe for
Corrosive Chemical Waste

Use this pipe in gravity-flow applications that involve highly-corrosive chemicals–it is NSF certified for use in corrosive waste systems. Pipe is made of CPVC, which has better chemical resistance than ABS plastic to stand up to acids and other harsh substances.

Expansion Joints with Socket
Connection for Plastic Pipe

Reduce stress, vibration, and noise in your plastic socket-connect piping system by creating a point of flexibility.

Tubing and Tube Fittings

Brass Push-to-Connect Fittings for Copper Tubing

Choose these metal fittings when you need better durability than our plastic push-to-connect fittings.

Socket-Connect Fittings for
Plastic Tubing—Drinking Water

Use these nuts with brass compression fittings to create a seal on plastic tubing. They meet NSF/ANSI 61 for use with drinking water.
