DIN Valve Fill Station Adapter 4500psi/300bar with 20inches Hose Dual Gauge for Charging Scuba Tank Paintball PCP Airsoft Diving HPA Cylinder

I use this valve on a "buddy bottle" for my PCP air rifle. That small half liter bottle is enough for one good fill on my rifle so if I start with a full gun I get around 100 shots between gun and bottle. Which is more than I've ever needed. I rarely fill from the bottle as it's easier on my compressor to fill the rifle to 3600 PSI than it is to fill the bottle to 4500 PSI so I just top off the rifle from the compressor as needed. Which means this valve sits for long periods of time without being used and so far it has held pressure perfectly and flawlessly. One thing I particularly like about this item is that it has a seperate one way fill valve so I don't have to fill the bottle through the main air hose. Just connect the compressor to the fill valve, turn it on and let get up to speed, close the compressor bleed valve and let it fill. This way the compressor is never struggling against bottle pressure to fill the bottle which is VERY important for compressor longevity. The compressor just has to load up the feed line and filter to the point where it cycles the one way fill valve open instead of trying to fight bottle pressure both ways. Something I've noticed is that due to compression heating the bottle fills but as it reaches ambient temperature it shows a small (350 PSI or so) pressure drop. If I top off the bottle after it cools down good then it stays at full pressure until I use it. Which again is very seldom so I can see that the bottle is holding pressure for extended periods of time. The single complaint I might have is it would be nice if there was a ring, stud, loop or hook, or some way to attach such a thing. So that I could hang the bottle safely on my shooting bench out of the way. This is a very minor quibble and I solved it with a cable tie holding a hook but ... It would be nice to have because the temptation is to hang the bottle by the feed line and I don't think that's an optimal solution. That's all I can ask and expect from such a device and this was one of the most economical options available on Amazon. I'm a happy camper.

Good quality valve. Package arrived with no damage. It was well packed in a small box in a padded amazon envelope. Installed on a 6.8L carbon fiber tank, filled to 4,500 psi and left for 24 hours. Used foam from dish washing liquid to check leaks and no leaks detected. The valve is of higher quality than most other valves sold on this platform. The gauges glow in the dark, a plus for me as I mainly do my activities at night. It fills my pcp bottles slowly with much control from the turn knob, compared with my other valves which allows a rush of air with slight openning of the valve, which caused problems with my pcp pressure gauge. For installing the fill hose from the valve, use the clear o ring instead of the white plastic ones. Both will work but the white plastic one will leave much of the thread outside. You'd want as much thread going inside the valve. Use a bit of silicone oil/grease on all orings. Very satisfied with this valve.

Works good ,no leaks , so far so good ,great value and quality.

bueno cumple su función en el tanque de 2.5L

Fits most pcp air tanks. So far no leaks or issues. Good build. UPDATE…I am using this on a Acecare 6.8 L tank and have had no issues with the Aopkeo fill valve station. I pump it up to 300 BAR /4350 psi and works fine with NO leakage. Gauges are accurate and unit is built very well and have filled my tank several times with no issues

Excellent quality and the gauges readings are actually colored showing pressures, and pressure readings on psi.

Both gauges are reading 100 bar lower than the true pressure. This is dangerous if you rely on these gauges for filling pcp. Valve and whip seem good if the gauges read correct pressure. The attached pictures show the gauges after a 300bar 4500psi fill and they are showing 200 bar and 3000psi.

Nice, does what it’s suppose too. Guages are a little small.
