In this video I'll be making a valve and a connector for a manometer and a fill nipple for a stainless PCP tank, the maximum pressure is 4000 PSI, but to ensure safety I recommend 3500 PSI. Keep following this series of videos and you'll see the finished version soon, it will be really powerful in just 4,5mm. I am expecting around 1100-1200 fps minimum using a 15.4 grain slug.
