PROBLEM WITH NIPPLE ADAPTER FOR MARAUDER BP1763 .177

[Luca B.]

Hello fans of Crosman products, I am asking for help with a problem I have with my .177 MARAUDER rifle. When I load the tank, the inlet valve receives air and when the tank is full and I try to vent the hose of the scuba tank, the rifle magazine empties completely. I think the fault lies with the o-ring of the NIPPLE ADAPTER code. 1761-106 and that it has worn out, even if it doesn't seem like it. Original spare parts cannot be found in Italy and I would be grateful if someone could provide me with the correct size and type of material this o-ring is made of, so I can try to recover it somewhere. I hope I have identified the real problem, and if anyone tells me if it could depend on something else I will gladly accept information.
Thank you in advance for your help

Try a drop of silicone. Drop a drop of silicone on the inlet of the gun. Fill the gun and release the pressure quickly not slow. This will lube the o ring. If problem still happens just change the fill adapter.
