This trapezoidal adapter is the only one in the world that comes with a safety valve hole to minimize the risk of gasket bursting and uncontrolled pressure equalization when disassembling a pressurized Co2 cylinder.
The adapter is supplied with two food-grade gaskets. The flat gasket is made of NBR rubber and expands under the pressure of the CO2 to achieve maximum tightness. When removing and replacing the CO2 tube, the gasket will swell further, so replace the gasket with the extra one provided. Let the used gasket rest for a couple of hours and it will regain its original shape and can be used again.
Always use seals of the same type and size to ensure function and safety.
The trapezoidal adapter is delivered with a basic setting, which means that the Allen screw in the middle is adjusted so that it opens the valve on the 425gr Co2 bottle at the same time as the O-ring seal seals. This may need to be adjusted with the included Allen key.
