New member. How can I get one of these one way valves from the member you got it from? Please let me know.

One way valve for filling scba tanks.
- Thread starter Fglass
- Start date
Look at the fourth photo of the male fitting - it includes a one way fitting held in place by a spring and a retainer. With that in, air flows into the fitting but not back out. The beauty is that it is removable for either replacement of the o-ring, or to have the fitting work without the one way function.
The description could be better, but that how it works . . . .

This setup has worked well for a few years now. It leaves my water trap and carbon filter completely full of air for months at a time and I can connect / disconnect guns without losing pressure and start up my compressor with no load without emptying the large water trap and carbon filter cylinders. Total cost was about $35 back when I made it, not including hoses, the water trap or the other connectors not called out. The hoses and orange water trap (barely visible) behind and below the shut off valve are not part of the system.

I went a bit of overkill on my filtration after getting moisture in my guns, no worries now. Did a simple male-male one-way fitting, with fittings off Amazon, into the center condolence filters. (Blue has color changing silica beads, Gold has moleculer seave) Can't remember where I sourced parts for the valve assembly coming out the gold, but it has a one-way bleeder, barely seen behind hose in 1st pic. Portable and can keep filters pressurized when disconnected. Removed the one-way out of the gold valve on the tank so can use it for filling tank, or teathering. I'll even switch between refilling the tank and direct filling guns at the range if I take more than one.
I believe we've just got to figure out what works best for our own purposes. I simply cobbled this together in stages till I figured out what what worked for me. Worst problem is remembering to close a bleeder back off before opening a valve and wasting air.
My range is on my back 40 so I'm not really traveling anywhere with this under pressure.

Better safe than sorry. Moisture cost me a regulator in the big bore. Then I bought the tank, and other guns. Don't have or need A/C, but humidity is an issue. Especially going to the range after a rainy day.

If they were available 1 1/2 yrs ago I would have gotten the GX fitler first. Probably would have been good enough. But I do tend to over kill everything I do. My GX4, just 100 hrs, no issues and deadheading within a few seconds of new.

Simple can be great. What did you use so you can disconnect your gun without losing the air in water traps / filters between the pump and the gun?

OK, stupid question. Which way does the air flow, toward the threaded end or the Foster end?
