Throwing a question around in a couple places, getting a couple different points of view.
I'm making a couple caps for Automag X-valves. They remove the on-board regulator to save weight and size, and make the usual tank-mounted or foregrip regs less redundant.
The X-valve has a vent in the side, for whatever useless reason, that needs blocked off. I made a pin that holds this in place and plugs the rear charging hole, and this ends up slowing the charge rate significantly.
The solution would be to either make a modified on/off assembly (basically converting it to a Classic valve), or the plug through so it can feed from the rear.
I just can't tell if the original regulator pin actually cuts off flow at any point. If I drill a 1/16" hole through to allow air to pass through this pin, would it hold the bolt forward, or does the bolt reset quickly enough that the pressure wouldn't have time to build? This method would save me a lot of trouble, and unfortunately the valve and my equipment won't allow me full-pressure tests.
As for the on/off assembly, I will need the O-ring's either way, and will have a tough time tracking them down. The outer one should be easy to measure, but the inner one is being a pain. I can tell it's .201" OD (IIRC), but I've always worked with O-rings by measurement, and not exactly sure what I should order.
I'd just order from a AGD part supplier, but I'd use enough of these a box from McMaster Carr would work better.
