Hw100 leaking through barrel port

[smecky 52]

Any ideas how to fix its a 22

If its leaking through the barrel when the rifle has been charged then you have foreign matter on the firing valve seat. If you havent cocked it and you are trying to fill it from empty then air will escape through the barrel. if there is air in the resevoir and its still leaking then there is dirt on the valve seat

Yes it's leaking when the cylinder is attached. Both when cocked and not cocked. Is this a quick fix?

the 12x1.2mm O-ring on the valve block is goosed mate....

Is that a 12.1 or 12.1.2mm and where can I them.

 

Thanks

12x1.2 is the original size HW put in as a crush fit

12x1 is the recommended replacement size as an "upgrade"

 

Have a look for your nearest bearing/seal suppliers mate

Do I need to put any sealing stuff on the seal and also what do I clean it up with. Cheers

Replace the 12x1.2 with a 12x1

Wipe clean with a rag
