NEVERMIND- after thinking about it I will just use a 1/2" coupler…
I am having one problem after another with this install. The OB2 compressors I bought each have a check valve that came installed on the compressors. I also have two short braided leader hoses. It looks like AZ intended for me to connect the leader hose to the check valve, then use the leader hose AND included fitting to the tank. The fitting is 1/2" on one side (the tank side), and I assumed the other side was 3/8" but that is too small. I need to extend the hose as 16" is not enough room between the compressors and tank. I had planned to use a male push connect fitting on the end of the braided leader hose (is it 7/16?), and use 1/2" tubing from there. I know they get hot, but I think the leader hose will keep it from heating up the plastic tube.
Can anyone tell me what size the female end of the hose is that comes with the OB2 compressors? I’m thinking it must be 7/16? (because 1/2 is too big and 3/8 is too small), if it is 7/16, I cannot find any 7/16" male threaded 1/2" tube push connect fittings???
