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.

Also known as Pressure Class 200 fittings.

These fittings have excellent resistance to stress cracking and have better corrosion resistance than most stainless steel alloys.

This Type M tubing has the thinnest walls of all our copper tubing for drinking water. It withstands pressures up to 980 psi.

Copper tubing has good corrosion resistance and excellent heat transfer qualities.

Often used in heating and cooling systems, this tubing insulates refrigerant to efficiently transfer heat between components.

This tubing has special markings to identify it as a gas line.

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

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.

The addition of phosphorus makes 122 copper easier to weld and braze than 110 copper. It has excellent resistance to corrosion caused by water, soil, and weather, making it the go-to material for plumbing and underground applications.
