Does anyone know the internal diameter of the pipe that fits on here (attached pic). I forgot to fit a one way vacuum valve so want to add one now but can't access this pipe very easily to order the right size. Thanks, PG
That's perfect Kruger, internal of the pipe that fits on or the external of that stub. I now can be sure and order a one way to fit 10mm. Cheers mate. How's the swap coming on?
