30MPa Air Compressor Pump 110V PCP Electric 4500PSI High Pressure System Rifle Bought this brand new and it worked about 20 times the last few times it took longer and longer to fill a small tank then no pressure. The machine starts runs sounds the same but no pressure. I took it apart and everything is perfect except for the seal on the upper piston. It should be an easy fix but i and thinking it might have to be done every 20 hours and for me its just no worth it. Any questions just ask.
