What sizes are copper joints? In the plumbing trade, the size of copper tubing is measured by its outside diameter in millimeters. 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.
How do you measure copper pipe fittings? Something that you can do specifically with copper pipe is to measure it by getting one pipe and inserting it into a fitting and then marking one of the ends. This can give you a more accurate measurement than a tape measure.
Is copper pipe sized by ID or OD? The nominal size of copper pipe is always smaller than the OD measurement. 1/2- inch pipe is the measurement of copper pipe that is 5/8 inch OD. The ID is affected by wall thickness.
What is the most common copper pipe size? The most common copper pipe sizes are ½ and ¾ inches. Type M ½ inch measures 0.028” in wall thickness whereas type L ½ inch measures 0.04” in wall thickness. Type M ¾ inch measures 0.032” in wall thickness while type L ¾ measures 0.045”.
