Abstract
For grasping and rotating a tube having a flared end and a rotatable flare fitting thereon a chuck carries a number of pivoted clamps movable radially inwardly against the fitting. An opposing pilot on the chuck enters the end of the tube to axially bear against the inside of the flared end, thereby clamping the rotatable fitting against the tube between the clamps and pilot for a firm grip on the tube end. The clamps and pilot are driven into opposing gripping relation by a slidable chuck housing sleeve which, in turn, is axially driven by a non-rotating thrust block. The housing sleeve, clamps and pilot are all carried for rotation on a driven shaft.
