Does anyone know what the thread on the nut is that is used on a 32mm waste compression fitting?
The 32mm (or 1.25") is what used to be the inside diameter of the pipe going into the fitting (but pipes have become thinner walled so this is no longer true) so this has no relation to the thread on the compression nut.
I could measure the outside diameter and assume it is a BSP type thread but I wondered if anyone knew what it actually was. All I have managed to find is wiki saying the nut is 53mm
