Capped GT Ring Sealing System
The Greene Tweed capped G-T ring (CGT™ Rings) is a double-acting, high-pressure piston seal that combines the space-saving and non-extrusion features of more conventional compression-type seals with the low-friction, long-life characteristics of o-ring energized TFE cap-type seals.

A positive seal that offers a high degree of sealability in both high- and low-pressure environments, the CGT™ Ring is designed to handle temperature extremes, a wide variety of fluid media, and larger than normal clearances — yet it requires a short axial length gland, and assembles and installs easily in the shop or in the field.

Features & Benefits

Clearance Limits- Wider clearances can be used when designing with the CGT™ Ring. This allows for the use of wear rings that eliminate the possibility of piston and bore damage due to metal-to-metal contact.

Space Reduction- The CGT™ Ring is ideal for use on components where axial space is at a premium. When replacing single or multiple lip seals, a substantial reduction in piston length can be achieved (even with the addition of wear rings). This reduction does not come at the expense of clearance limits or performance.

System Contamination- Where grit may become trapped between seal and dynamic surface in conventional systems, the CGT™ Ring’s anti-extrusion rings serve as bore wipers, pre-cleaning the seal path and significantly reducing contamination caused wear.

Surface Finishes- Recommended TFE caps – 4 to 16 RMS; elastomeric (hydraulic fluids) – 8 to 16 RMS; elastomeric gases) – 8 to 12 RMS; static – 32 RMS max.
