Hmmm, anyone tried this…

or would it benefit anything???
If you put an o-ring on the outside of the tophat to seal the slide connection between it and the hammer, would that buy any more power/quietness, or does the air not come out there. I know some guys are making an o-ring mod where the shaft comes out of the valve, but I didn’t know if an o-ring on the tophat would do anything to help with escaped air/noise. I also remember someone making slap-mods for the hammer, but I am talking about sealing the tophat where the hammer slides over it.

thanks
