ACT® Ring

Greene Tweed has taken the concept behind our renowned AGT® seal, optimized the design of the elastomer and anti-extrusion rings, and developed an Advanced Concept T-ring (ACT®). The ACT® ring is designed with converging sides in order to promote lubrication for reduced friction and wear, with an apex for force concentration under low-pressure conditions to optimize sealing.

Features & Benefits

Improved gland stability, resulting in reduced stress in the elastomer for enhanced sealing performance
Specially tapered elastomer side wall design reduces friction and promotes efficient seal lubrication, ultimately leading to longer seal life
Hydromechanically activated, anti-extrusion rings for enhanced extrusion protection at all sealing pressures
The wide static footprint of the “T” geometry cross-section eliminates spiral failure
Retrofits existing MIL-G-5514/AS4716 and AS4832 glands
Metric series available for metric-sized designs

Applications

Accumulators and reservoirs
Actuators (e.g., door actuators)
Flight controls (e.g., spoilers, rudders, aileron)
Landing gear actuator subsystems (e.g., end caps and static seals)
Landing gear spare dynamic seals
Landing gear dynamic seals

Configurations

For pressures up to 4,000 psi (276 bar), we recommend standard diametrical clearances per MIL-G-5514/AS4716, providing proper gland lengths and materials are selected.
