This is a long shot - I have a Bostitch SB-150SX that I only use occasionally so I'd prefer to fix it rather than buy a new one even tho' the replacement cost wouldn't be too much for the same quality. The trigger air valve is leaking air badly and should be replaced but no one, as far as I've been able to search has one since it has long been discontinued.
I've tried cleaning and greasing the o-rings without success. Does anyone have any suggestions? Maybe try to id and replace the o-rings?
Thanks.
