The unique G-T^® Ring provides a compact double-acting seal for
use in heavy-duty applications that previously required a more bulky type of seal, as well as for retrofit in standard grooves designed for O-rings with one, two or no backups.

This proven seal combines a tough, resilient, T-shaped sealing ring with precisely-dimensioned pressure actuated nonextrusion rings for use with pressures ranging from zero to 20,000 psi and higher.

Performance, reliability and economy as a piston seal are unequaled with no piston drift and minimum piston length. This seal eliminates two major sealing problems:

1. 1 The G-T Ring sealing element is protected from extrusion so that it seals satisfactorily when clearances must be abnormally large or where pressures are high.
2. 2 The unique G-T Ring configuration prevents seal roll and spiral failure.
