A double-acting rod or piston seal with an outstanding combination of easy installation, low leakage and long service life for exceptional performance in many static and dynamic sealing applications. The G-T® ring offers better extrusion resistance and eliminates spiral failure when compared to an O-ring and Back-up ring assembly.
The G-T® Ring is a static or dynamic seal in “rod” or “piston” configurations for demanding oilfield applications, e.g., cylinders, jacks, intensifiers, tensioners, BOPs, logging equipment, jars, shock subs, bumper subs, pumps, valves, and well head equipment.
The unique G-T® Ring provides a compact, double-acting seal for use in new designs or existing applications where o-rings are failing. The G-T® Ring can be retrofitted into standard grooves designed for o-rings with one, two, or no back-ups. This proven seal combines a tough, resilient, T-shaped ring with precisely dimensioned, pressure-actuated, anti-extrusion rings for use with pressure ratings in excess of 40,000 psi.
