The nominal size of copper pipe, whether supply lines or DWV, is always 1/8 inch less than the OD measurement. For example, copper pipe that measures 5/8 inch OD, is called 1/2- inch pipe. The ID varies because wall thickness varies. Type K has the thickest wall, followed by Type L, Type M and DWV.
In the plumbing trade the size of copper tubing is measured by its outside diameter in millimetres. Common sizes are 15 mm and 22 mm. Other sizes include 18 mm, 28 mm, 35 mm, 42 mm, 54 mm, 66.7 mm, 76.1 mm, and 108 mm outside diameters.
Thereof, What is the OD of 1/2 inch copper pipe?
Also to know is, How do I know what size PEX I need? In general, the greater the distance from the manifold to the fixture, the wider the PEX tubing should be. A 3/8-inch line is sufficient for lengths up to 250 feet; 1/2-inch line will deliver adequate water pressure up to 350 feet; and 3/4-inch tubing is necessary to run a 500-foot line.

Is type M copper rated for pressure?
The smaller the pipe diameter the greater the pressure rating. As two extreme examples, Type K drawn tube ¾ inch in diameter has a rating of 1,278 psi. In contrast, four-inch Type M annealed tube has a pressure rating of 251 psi. That’s quite a difference.

What is the difference between Type L and Type M copper pipe?

What size is copper pipe in a house?
In most cases, the main pipeline from the street to your home is either 3/4 or 1 inch in diameter, supply branches use 3/4-inch-diameter pipe, and pipes for individual components are 1/2 inch. Remember that water pressure decreases by a half-pound per square inch for every foot pipes extend above your water supply.
