30MPA High Pressure Air Test Pressure Adapter Connector Airforce Adapter 8mm Fill PCP Thread M18x1.5

My Theoben PCP rifle does not have a quick fill nor a pressure cage. The Buddy bottle uses M18x1.5. I was able to use this to put between the bottle and the screw adapter to add a pressure gauge and quick fill. Had to drill a hole in the stock to access the quick fill. The gauge sits straight up so that I can see if around the barrel. Works absolutely perfect. Even came with extra gaskets. I ended up putting a better 1″ pressure gauge on it as the one it comes with is fair. It is accurate but only shows MPA. I prefer PSI. Also my bottle only supports 3000 psi and this gauge was to 4500 psi.
