T-Seals are compact three piece double acting seals consisting of a T shaped elastomeric element and two rigid anti-extrusion rings. These compact sealing elements are designed to fit into simple O-Ring grooves and are frequently used to retrofit O-Rings that are failing. The T-Seal’s geometry prevents spiraling and because it utilizes rigid back-up materials, it can withstand very high pressures and large extrusion gaps. T-Seals can be used in dynamic or static applications in many oilfield applications including intensifiers, jacks, cylinders, tensioners, shock subs, bumper subs, valves and pumps. GMORS’ T Seals can be either piston type or rod type.
