Greene, Tweed's Aerospace SFSs (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. The SFS consists of an L-shaped elastomeric sealing/energizing element with a mating back-up ring. At zero or low pressure the SFS'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 mating flat surface.
