I had a 3D printed kit from a guy on here and it just didnt last causing leaks in use as the plastic delaminated and cracked on all the parts so in the end I bought plumbing pipe ends and put in my own schrader valves and made flat plates for the exhausts from 10mm alloy and reused the rubber seals in the kit. It really wasnt that hard to do. Take an inlet rubber to the hardware store to find what plumbing end caps / pipe (with and end cap on it) fits and then make a plate. really not hard. Buy a nice low pressure (you only need 5psi to do the test) gauge and use a hand pump on the other valve if you put one in each inlet etc.

And when there is leakage in the kit it's mostly on the exhaust side. Difficult to seal 100% when rubber is wearing down. For this I bought some rubber stops. Cut them in half so the matal plate can still be used while putting the rubber stop over the exhaust port. No more leaking problems over time  And also handy for painting a tank. www.rubbermagazijn.nl/rubberstop-grijs-d-36-44mm-h-40mm-set-5-stuks_grijs_21940.html |
