About Metal Tubing

General Purpose Copper Tubing

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

Medium-Pressure Copper Tubing for Drinking Water

This Type L tubing has thicker walls than Type M tubing. It withstands pressures up to 1,500 psi.

High-Pressure Copper Tubing for Drinking Water

This Type K tubing has the thickest walls of all our copper tubing for drinking water. It withstands pressures up to 1,900 psi.

Low-Pressure Copper Tubing for Drinking Water

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

Cleaned and Capped Copper Tubing

This tubing comes cleaned and capped to prevent moisture and dirt from contaminating the inside. It is also known as refrigeration and air conditioning tubing.

Insulated Copper Tubing

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

Brass Tubing

A soft metal frequently used with air, gasoline, natural gas, propane, and plumbing applications. Tubing is not as corrosion resistant as stainless steel.

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.

Press-Connect Fittings for Drinking Water

Connect drinking water lines with ease—these one-piece fittings have a built-in sleeve that crimps onto tubing for a leak-tight connection that doesn’t require heat or soldering. These fittings meet NSF/ANSI 61 for drinking water systems and are compatible with Viega PEX tubing.

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.

45° Flared Fittings for Copper and Brass Tubing

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They are also known as refrigeration and SAE fittings.

Medium-Pressure Pipe Fittings for Joining Dissimilar Metals

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.
