scba tank & parts

To fill your SCBA tank:
I assume you have a full size SCUBA compressor.... It use a DIN300 fill connection on it's hose assembly.

To fill your gun....has a gauge, bleed valve and hose....
 
If you get a Scott you'll need a CGA347 fill adapter (if it has a standard SCOTT valve). Check ebay & search "CGA347 fill adapter", you'll find MANY. You might want to put in the words "hand tighten" to find the ones that don't need a wrench (ROUND tank valve nut as opposed to hex). Most come from China where quality control isn't great but I've NEVER gotten one that was so bad it wouldn't work by replacing an o-ring or smoothing a burr. I'd much rather spend 40 some dollars than $100+ at other places, but that's me.
 
You could also build a CGA347 fill adapter yourself that would be a better quality than the chinese ones in my opinion. Here is what i built.

good to see this thread..I got mine from airgun archery fun in Canada.. it comes with a double connector to hook up to the compressor Foster fitting..
I have a survivair 30 minute tank and I am having a hard time finding a replacement valve for the tank.. mine is leaking at the gauge and it is built into the valve on the tank.. most are 5/8" or 7/8" thread where it goes to the tank.. mine is 1.125" same as 1 1/8" and I can't find the valve anywhere.. so if anyone has a idea I'd greatly appreciate it.
thank you
