Copper Pipe
We keep a range of copper pipe in sizes from 4 mm to 54 mm.
Metric copper pipe / tube dimensions are based on the outside diameter of the pipe.
15 mm is the most popular size, larger sizes (22 mm and 28 mm) are used for baths, storage tanks and boilers / central heating.
Smaller sizes of pipe (10 mm and less) are often referred to as "microbore".
UK copper pipe changed from imperial to metric in 1972 click here for information on the old pre 1972 sizes.
