What fittings can I connect together (building an air compressor) ? Answered
I'm building an air compressor out of fridge compressors, propane tanks and NPT fittings from ebay, everything was cool until I received a check valve I ordered before all the other stuff (because it was from another seller so no need for a group order :) for one item).
So I ordered a 1/8 female/female check valve (one way valve), and I measured the diameter with calipers, and it's not 1/8" (3.2mm) but a lot more, which makes sense, 3mm would be really tiny so now I don't understand how all of that works
here are the fittings that will compose the system (those are 1/2 I guess but I will order 1/4 and 1/8 as well to make the complete circuit (around 20 fittings total):
here is the check valve I already ordered (1/8 BSPP):
I also noticed the valve is linear while the fittings appear to be the shape of a cone, will it matter ?
Thanks in advance for any help ;)
