About Metal Tubing

General Purpose Copper Tubing

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

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.

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.

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.

Copper Tubing with Coated Interior

The inside of this tubing is lined with 99% pure tin for added corrosion resistance.

Copper Tubing with Coated
Exterior for Natural and LP Gas

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

Insulated Copper Tubing

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

Standard-Wall Copper-Nickel
Threaded Pipe Nipples and Pipe

Also called close nipples, these Schedule 40 nipples are threaded on both ends to the center.

Copper-Nickel Unthreaded Pipe

Also known as Pressure Class 200 pipe.

Copper

Super-Conductive 101 Copper Tubes

With 99.99% copper content, 101 copper has higher purity than 110 copper, resulting in superior electrical conductivity. It's commonly called OFE and OFHC copper. Use it in electrical applications, such as for coaxial cables and terminal lugs.

Marine-Grade Copper Nickel Tubes

Commonly used in water treatment plants, these tubes withstand salt water and can be used to make shims, ferrules, and washers.

Weldable 122 Copper Tubes

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.
