I was thinking the same. The whole setup blows my mind, but I did think if I could start finding a few parts it might all magically become clear. The two contenders I found are ebay numbers 253005988896 and 253005988896. I don't know if 6mm would be the right size or if either of them are the same as Robert used. Superb setup regardlessoddsocks wrote:Hi Robert, I realise this is an old thread but i missed it at the time.
Do you have a supplier / description for the one way vacuum valve that you fitted?
Thanks

If I get enough free time in the few months I'll have a go at making a setup so its ready when I actually have a vacuum project.

Although considerably more expensive I used one of these.

In practise the hysteresis is about 2-3 psi.
The adjustment screw is down the sensor input which is a bit weird.
I set it to max which is about 13.5 psi - plenty for the application.
