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

this a solid built adapter. has dual gauges so you can see the pressure on both sides of the valve. perfect for larger tanks to be able to refill smaller paintball tanks or PCP guns. only gripe is the lack of instructions. other than that and if you know what you are doing you will find this kit a very decent deal. I have mine installed into a scuba tank and use it to quickly refill paintball marker air tanks.

There are 2 main thread sizes that tanks/regulators may use; M18*1.5 or 5/8"-18UNF for input threads. Make sure you check your tank thread size before buying. No instructions came with this fill adapter. The thread on the fill hose going into the fill station adapter is too long, you also have to guess what o-rings you need so it doesn’t leak.

WHYThe hose on one of my fill stations got damaged. By the time you replace the hose and connectors it’s almost the same price as a new fill station adapter and hose.INITIAL IMPRESSIONSHands down this is the best fill station adapter I’ve owned. To me the main selling point was the main know on top, it is easy to use and turn by hand and has very granular control of the pressure.PROSEasy to useGood quality hose and connectorsGranular control of pressureCONSNothing really, other than make sure you pick the right size adapters for your specific needsOVERALLThis worked perfect for my small 1L pcp bottle

I have been around PCP airguns now for a couple years so I'm not a total newbie, BUT SOME directions to guide and warn you could actually save your life with this thing.If I have 4500PSI in my bottle, the last thing I want is a FAILURE!SO, I would have really liked some basic directions like how much to torque the valve to the tank. Then the refill hose needs installed. 2 different gaskets were provided that could fit, so which is it?? I used one of the white nylon ones. Not sure if that's right or how much to torque THAT connection.So, I'm a little dissapointed here. Otherwise, I'd have given the hardware 5⭐️.The reason I knocked off 2 stars is because if this valve or the installation fails, it can REALLY cause a bad day for someone. Fortunately I believe I'm pretty mechanically minded and I THINK I got it right, but who knows! 😉I think the price at $50 is very fair....if it came with some directions.

It works exactly as advertised and has a larger turn knob than others that makes it easier to make fine adjustments that I really appreciate. The workmanship is also on par with others I've used in the same price range. It came well packaged and even had plastic protective covers over both gauges (see photo)It's partly my own fault for not paying closer attention to the gauges before purchasing, but the 1 star deduction is for the size of the gauge scale. It really is much smaller than it appears in the listing photos and much smaller than what I'm used to with similarly sized gauges (see photo). They do seem to be quite accurate, but they are a little difficult to read.All-in-all this is a budget friendly fill adapter that works exactly as advertised.

Works great, love having 2 gauges, one for what's in the tank one for what you're filling. My old one only read while filling, so you didn't know what was left in tank. I installed it on a 500cc tank and waited a week to review...no leaks! The fill inlet has a check valve so no need to try to guess when your compressor is close, just connect, turn on and fill. So nice, would buy again.

Feels very well made. I lost my last one somehow. Misplaced I guess. This is slightly better so I appreciate having an upgraded solution.I like the large knob for precise control.It was well packaged for shipping.

Although the product title describes this as a "DIN Valve Fill Station Adapter", there is nothing about this valve that implies fill station or DIN valve. This valve is for mounting into a pony tank and refilling smaller bottles. I attached it to a 1.5 liter bottle and it fit just fine. The button gauges are small and difficult to read without my glasses, but accurate. This is not a valve I would use on anything I was taking underwater, but it works well for filling small bottles for other uses like paintball. It is well-constructed from quality material.
