Is 1 2 Inch 15mm 1 2 pipe refers to the internal diameter 15mm pipe is the external diameter In my experience they are so similar that you can even use solder fittings without a worry so using 15mm olives on 12 pipe isn t a problem
The OD of 1 2 and 15mm are so close to each other that 15mm compression fittings can be used on 1 2 pipe It s a different matter for 3 4 pipe but you can use 22mm compression fittings on 3 4 if you replace the olives with imperial ones With the added wall thickness of the pipe 1 2 copper is more or less it s actually a fraction more 15mm outside diameter The threads for fittings used in plumbing are based on these standard pipe sizes and are referred to as BSP British Standard Pipe threads

1 15mm pipe is almost exactly 15mm in diameter 1 2 is a little larger in diameter The best way to measure diameter is with a set of vernier calipers but if you don t have these then measure the circumference and divide by pi which is generally accepted as 3 14159 For example 1 2 inch pipe is almost exactly the same physical size as 15mm and the two sizes can be joined WITHOUT a special adapter a 15mm coupler or a 1 2 in coupler both work OK That is not what you might expect if you know that 1 inch 25 4 mm endgroup
Can you use a solder joint If so that s probably the easiest go to any most sheds and you ll find a 1 2 to 15mm coupler Almost certainly you ll find compression equivalents too Is a 1 2 male thread the same as the 15mm male thread on a compression fitting Thanks

Whilst most 15mm compression fittings are 1 2 bsp some earlier ones had finer threads the same cannot be said for 10mm and 8mm As an oil engineer I encounter many 10mm and 8mm fittings and am amazed at the difference both in thread pitch and also diameter There is no difference The outside diameter is the same The wall thickness may vary though If you need to find a tradesperson to get your job done please try our local search below or if you are doing it yourself you can find suppliers local to you Select the supplier or trade you require enter your location to begin your search
