Gamo Urban seal kits

[cbourbeau32]

My Urban sprung a leak. It's leaking from the area where the fill probe goes. I have a Harbor Freight Metric o-ring kit but I can't find an exact match for any of the three o-rings that go on the manometer end of the fill tube. I can order the replacements off ebay but they ship from the UK so it would be two weeks or so before I received them. Does anyone know the exact sizes of the ones that I need? The one that the manometer screws down onto is way thicker for its size than the others. Any help would be appreciated!

How long has your gamo been leaking?
Mine leaked from the time I bought it until I found that the gauge itself was not snugged down. Since then there have been no leaks.
You may not even need orings.

It just started a few days ago. I filled it up and the next day it had leaked off. Before that it held pressure (perfectly, with no leaks) for weeks. I filled to near max psi/bar but I don't think I went over.

Short and simple….ignoring the English accent.


Haven’t tried to get it off on a fully assembled rifle….might be just enough room to pass the big LDC,  might need to remove the barrel.
