Product Description
The MS28774-226 is a PTFE packing retainer (backup ring) conforming to SAE AS8791 specifications. This scarf-cut, single-turn component prevents O-ring extrusion in hydraulic and pneumatic systems operating under high pressure. Installed adjacent to elastomeric seals in aircraft actuators, valves, and fluid system components, the retainer supports the primary seal and extends service life.
The PTFE material resists extrusion while maintaining compatibility with hydraulic fluids and pneumatic media. Installation follows component maintenance manual procedures for proper seal stack configuration.
