I recently acquired an air compressor and have been trying to restore it, I believe its a Cosmo air 2 horse mini. It's missing the outlet pipes and gauges, which I have found, however they all seem to be ones that screw on and this compressor only has an odd sized, male, quick release component. I was hoping someone on this forum with better knowledge could point me in the right direction for finding this mysterious part. Apologies if this is incorrect in any way as I'm new to this forum.
