I just purchased a viair 90p which I like pic attached. It is set up to connect directly to the tires which normally would be great. I made a 4 air system for inflating all 4 at same time which I also really like. Out of the box they are not playing together. What do I need either on the 4 air or the viair 90p to connect them - I don't know what would be the best/cheapest method. How can I attach a push to connect coupler to the compressor? Would I just use a hose fitting on the viair 90p and the universal coupler screws on to that hose fitting?
Thank you - 1st air compressor
