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.

Medium-Pressure Pipe Fittings
for Joining Dissimilar Metals

Use these unions to connect different metals in a piping or plumbing system. They have a gasket with a plastic sleeve that inhibits destructive corrosion.

Tubing and Tube Fittings

Solder-Connect Fittings for Copper Tubing

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

Cleaned and Bagged Solder-Connect
Fittings for Copper Tubing

When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.

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.

Brass Push-to-Connect Fittings for Copper Tubing

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

Plastic Push-to-Connect Fittings for Copper Tubing

Made of plastic, these fittings are lightweight compared to our brass push-to-connect fittings.

Clamp-On Fittings for Copper Tubing

Use these fittings to make leak-resistant connections without threading or soldering. Slide them over tubing and turn the end nuts to compress the gasket.

Barbed Tube Fittings for Drinking Water

Connect these fittings to tubing with a ring and a crimping tool (both sold separately). Safe to use with drinking water, these fittings meet the strict standards of NSF/ANSI 61.

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.

Tube-End Weld Nuts

About half the strength of medium-strength steel coupling nuts, these metric nuts are for light duty fastening applications.

Left-Hand Threaded Tube-End Weld Nuts

Use these tube-end weld nuts with left-hand threaded fasteners.
