FPH Seal™

Greene Tweed’s Fireproof Hydraulic Seal (FPH Seal™) provides excellent high- and low-hydraulic pressure sealing in static applications for fireproof rated equipment (1093°C/2000°F minimum average for 15 minutes). Greene Tweed recognized the need for a new hydraulic seal design that would meet fireproof requirements, while providing static sealing capabilities in fire and flame-resistant equipment, such as thrust reverser actuator systems (TRAS), fuel systems, and thrust vectoring/nozzle systems.

Features & Benefits

Sealing system passed fireproof testing (2000°F avg. for 15 minutes) for hydraulic sealing applications on aircraft
Uses standard aerospace glands in accordance with AS4716 and AS5857
Alternative to traditional fire shields that are typically heavy, bulky, easily damaged, costly, and require assembly

Applications

Thrust reverser actuator systems (TRAS)
Fuel Systems
Thrust vectoring/nozzle systems
