I want to seal between a shaft and housing. I internal pressure is 2psig and will hold N2 and potentially corrosive gases. The shaft will be raised and lowered at times with a 1/2″ or 2″ stroke. The shaft outside diameter is currently 0.5″ and the housing od is 1″. This could be altered to match stock bellows seals.

Thanks,
