Abstract
An apparatus for selectively gripping and rotating a part includes a selectively rotatable drive shaft assembly, a draw bar assembly and an expandable media positioned therebetween. Axial movement of the draw bar assembly relative to the drive shaft assembly selectively compresses the expandable media to radially expand the same for gripping the part and for coupling the draw bar assembly to the drive shaft assembly, thereby permitting the gripped part to be rotated. The apparatus preferably includes an adjustable metering valve to apply sealant to horizontally oriented threads on the part and further includes a wiper to distribute sealant along the threads and to uniformly spread the remaining sealant into the thread grooves.
