I need 3 male and 3 female quick connect/disconnects for my dsv/bov and my adv's. I don't own a lathe, and am most interested in something that screws directly into the fittings already in place. My rig is a homebuild so essentially I'm just looking for QD's between 3 first and second stages, much like a bcd connector, but flowing enough gas to breathe. I've built much on this rig, but really wish to out-source this particular component. Can anyone accomodate me?

Reasonable quality/ reasonable cost.
