Will the plug be made of brass? If your modding a pressure vessel, it won't be pressure certified afterwards, potentially a big bomb. I have made a couple of plugs for CZ200's out off brass, sometimes even replacing the original pressure gauge with one's used on fire extinguishers although they tend to be a bit weak and even blowing out. :zap: Remember that the vessel will swell when charged in different ways resulting in a blow out with the tube swelling more than the plug. You should compensate for this in your design. On the CZ's the threads are cut as a tight fit, compensating for the lesser swelling of the plug against that of the tube that is steel. Best advice is that you provide more information as to the rifle and the vessel fitted, what gas the vessel is intended for, at what charge you are going to charge it and if you will be charging the vessel through a regulator. Better be save than going to hospital if it fails catastrophically shooting a hole in the side of your pickup. :bang: |

pressure tube is off a falcon pcp air rifle normaly charged to 2700 psi from a divers bottle so no worries about it blowing up polecat |

An aerosol can is way less than 100 psi. and it took out an neighbors eye. |

Hi Lads I think Polecats air receiver will be fine its made for the job , BUT an ill fitting threaded plug is another thing all together with roughly ,1400Lb (+/- a little bit ) of force behind it :med: Rob |
