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.

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.

High-Pressure Nipples for Compressed Gas

Commonly used in high-pressure welding applications, these nipples connect your tank to the inlet of a pressure regulator. One side has a threaded pipe end and the other side has a rounded end that sits inside a threaded nut to make a threaded connection.

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.

Supported 45° Flared Fittings
for Copper and Brass Tubing

The flared end of the fitting nests inside the fitting body, providing extra support to the tubing. Fittings are also known as inverted 45° flared fittings.

Precision Steel Tubing

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

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.
