Abstract
A casing running tool capable of handling pipe and tubing has fluid power conducting channels leading from stationary to rotating components, through a swivel. The swivel has a plurality of fluid channels, each confined by dynamic seals that rub peripherally on mating seal surfaces. The seals are carried on at least one piston that is movable, on command, to carry the seals out of contact with the peripherally rubbing surfaces.
