Paintball Co2 Tank Adapter Compressed Air Fill Station Remote Switch ASA Adapter with 3000psi Gauge Black

But first I had to figure out how to use it. I thought the knob on top was a valve, but it works opposite as you would expect. Clockwise opens up the valve on the tank and counterclockwise, closes the valve on the tank. You use the bleeder valve on your compressor to release the pressure from the hose after you close the valve on the tank. Then you can unscrew the adapter off your tank with no air loss. I did it wrong a number of times before I figured out what I was doing. Update: I discovered something else. It seems you don't actually have to turn the knob on the top and open the valve on the tank to fill it. It seems the high pressure of the pump will automatically go into the tank and go through the closed valve. I'm going to have to experiment and see if opening the valve allows a little more pressure into the tank.

Arrived in one piece and no issues. Thanks

Worked well... the screw knob fell off the first time I used it as its only glued onto the shaft... I used epoxy to attach it back to the shaft.... now it works great.... Got me using paintball guns I hadn't used in almost 15 years. Definitely worth it, just plan on gluing the knob back on

Fits perfectly on my Tippman. You need a high pressure O2 cannister or pump to use it effectively though.

Item is as advertised and arrived on time. Product fit perfectly, but is at a 45 degree of fill valve. But the main problem is that there is no bleeder valve.

Garbage won’t work for my hpa tank and knob fell off

Easy to use, don't blow off caution..

Not exactly what I needed

Good quality and well built, did not use it for it's intended purpose but it worked for me

This is the second one I ordered and same issue no 8mm fitting or a hole to thread one in. Return in progress but do i dare try again. Third time lucky????

works great

I got my adapter but no quick plug at all so I paid for nothing
