The MS28774-326 is a tetrafluoroethylene (PTFE) backup ring from the MS28774 series designed to prevent O-ring extrusion in hydraulic and pneumatic system glands. This packing retainer installs in component grooves behind seals, supporting them against pressure-induced extrusion during operation. The PTFE material provides low friction and compatibility with mineral oils, synthetic fluids, and pneumatic systems.
Installation requires orienting the scarf cut per maintenance manual specifications and applicable groove standards for MS28774 backup rings. Commonly used in actuators, pumps, motors, and fluid power components across general and commercial aviation.
