While donning my dry suit today, I found that the input hose of my p-valve had broken off at the threads. Anyone know if this is a common item that is available in a local hardware store or if it is a Dive Rite only piece? Any ideas on the size and thread pitch? I don't think I'm going to be able to tell once I get it out. McMaster-Carr has some that look similar, just not sure which one I need.
