Copper tubing sizes

What is Type K copper tubing? Wall-thicknesses used for plumbing in the U. Seamless, round copper tubes for water and gas in sanitary and heating applications. The adapter adapts to standard male pipe threads and resists de-zincification.

Features a 5psi maximum working pressure and relies on a force or pressure to maintain flow.

How do I determine which size copper sweat fittings to use? Type M and Type L copper tubing help provide flexibility when working around obstacles. Type K is thick-walled to help complete applications that require maximum strength. Browse the wide selection of copper pipe and tubing at Grainger to help with a variety of plumbing and heating projects.

In the plumbing trade the size of copper tubing is measured by its outside diameter in millimetres. Common sizes are mm and mm. Other sizes include mm , mm , mm , mm , mm , 66.

Nominal: Used to describe copper pipe and fittings in plumbing terms.

Refrigeration grade soft copper tubing is sized according to the outside diameter of the copper pipe. This refers to the inside diameter of the pipe and varies by the thickness of the pipe. D in terms of HVAC sizes. Temper” describes the strength and hardness of the tube. In the piping trades, drawn temper tube is often referred to as “hard” tube and annealed as “soft” tube.

Tubing is telescopic with adjacent sizes. Type K pipe is available in a rigid and flexible form and can be used with flared and compression fittings. The Internal Area can be used to calculate velocities of fluids. These dimensions apply to carbon, stainless steel, PVC and seamless pipe. The string method (which measures the circumference of the pipe ) is probably the best way to determine your pipe diameter size.

Circumference is the distance it takes to go around the pipe once. Remove any insulation from the pipe. Using a piece of string about 6” long (or a cloth tape measure) wrap the string around the pipe once and measure. Use this guide to help you find the pipe and fitting sizes you need!
