G-T® Rings

Piston sealing solutions for demanding environments

Greene Tweed G-T® Rings are  available in rod or piston configurations.  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. For higher pressures, contact us.

Features and Benefits

  • Easy installation
