Greene, Tweed’s Static Face™ Seals are designed to eliminate sealing problems in face-mounted assemblies where large clearances can occur and/or pressures up to 10,000 psi (690 bar) are encountered. Engineered as a “drop-in” replacement for O-rings in seal glands with applied depth and length per MIL-G-5514, the Static Face seal consists of an L-shaped elastomeric sealing element with a hydromechanically energized mating back-up ring.
For the blind mounting conditions of pumps, valves and manifolds, use the “50” series designator for a press-fit backup that retains the seal within the gland for ease of assembly and field repairs.
At zero or low pressure the Static Face Seal’s elastomeric element functions as a positive sealing element, much like an O-ring. As pressure builds, this element transmits system pressure to the anti-extrusion ring forcing it against the gland wall and bridging any extrusion gaps that are generated as a result of hardware expansion.
Standard aerospace Static Face seals are designed for internal pressurization. Seals for external pressurization are available on request.
The part numbering system requires the use of the material designator tables found in the next column. For nonstandard designs contact GT engineering.
