I have just gotten a BOV for my Prism2. I am wanting to plumb it into my sidemounted bailouts,... however I want a locking quick disconnect so that I do not have to constantly take the hose off by wrench. Right now I am wanting to use a quick disscontect with a check valve to prevent water from entering the hose, because I frequently put my bailouts on when in the water. The problem arises that the check valve fitting is a 9/16" male, as is the end of the hose coming off the BOV, that's nto working out at all well. There is not enough room at the BOV to put QD at the BOV fitting (barely enough room to get the hose on). Right now my idea is to cleanly route the hose from the BOV to terminate in the male end of the QD (has the check valve) & have the female part of the QD attached to a very short reg hose that is connected to the 1st stage- fittings are proper on that end. My problem is the 9/16" male/ male ends.... I'm needing to find a 9/16 female/ female coupler,.. but can't find any such animal for reulator hoses. Any ideas???? The piece on the left is what I want to attach to the BOV side (because of the check valve position & the piece on the right is what I want to connect to the hose coming off the 1st stage.
