Hi all, I have two broken compressors both 50ltrs, one the motor is gone and the other the cheap manifold is broken (cheap casting) firstly I would like to swap the manifold from the sip one to the wolf one but the size of the manifold is different. The Sip one is measuring 17mm and the wolf is a 20mm screw-in. is there a reducer I could buy? secondly, could these receivers be joined? if so how? hopefully, the pictures have loaded. thanks
