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.

Insulated Copper Tubing

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

Precision Steel Tubing

With the lowest OD tolerance of all our steel tubing, this tubing is designed for precision applications.

Air Conditioning Hose

Use hose to charge and test your air conditioning units.

Air Conditioning Hose Sets

Each hose is a different color so you can differentiate your lines.

Refrigerant Hose

Made of nylon, this hose keeps refrigerant in but moisture out, protecting your air conditioning or refrigeration system from freezing or corroding.

On/Off Valves with Solder-Connect
Fittings for Refrigerant

Install these valves in HVAC and refrigeration systems to control CO2. For a permanent, leak-tight connection, solder them to metal tubing.

Threaded On/Off Valves for Refrigerant

Often used in HVAC or refrigeration systems, these valves are designed to control the flow of ammonia, nitrogen, and other harsh chemicals.

Refrigerant-Resistant Sleeving

Coated in acrylic, this sleeving holds up to rapid temperature changes, and it won’t break down from refrigerants, solvents, oil, or lubricants. Also known as hermetic sleeving, it’s designed to protect wires and hose inside air-tight motors, such as those used in air conditioners.
