Offer of Sale The items described in this document are hereby offered for sale by Parker Hannifin Corporation, its subsidiaries or its authorized distributors. This offer and its acceptance are governed by the provisions stated in the Offer of Sale . Make-Up For Leak-tight UltraSeal Assemblies: A positive seal is achieved by advancing the nut no less than 1/4 turn from finger-tight position. When a sharp rise in torque is felt, the sealing faces have met and the o-ring seal is compressed into its groove. UltraSeal is capable of repeated remakes; advance the nut to a fingertight position and wrench until a sharp rise in torque is felt. No axial clearance is needed to remove components from a system; therefore, other system components are not disturbed. Design The UltraSeal coupling is designed to effect a helium leak-tight seal when the face of the gland makes full metal-tometal contact with the face of the body, compressing the o-ring in the body groove. The UltraSeal gland face and body o-ring groove are precision machined to accept either metallic (S.S.) or synthetic o-ring seals. UltraSeal virtually eliminates turbulence and dead zones within the fitting. The bore diameter of body and gland are matched in all sizes, providing a smoother flow path. At no point does the O-ring seal intrude into the flow path. Disassembly Position the o-ring UltraSeal Removal Tool against the seated o-ring and advance the nut to fingertight position. Continue to advance the nut until a sharp rise in torque is felt. The removal tool shoulder will seal against the body face preventing any over torque damage. The o-ring will pinch" and release from the sealing groove.
