Product Description
The MS28782-5 is a PTFE backup ring (packing retainer) conforming to SAE AS8791/MIL-R-8791 specifications. This scarf-cut ring prevents extrusion of O-ring seals in hydraulic and pneumatic system components. Installed in gland grooves adjacent to the primary sealing element, it protects packings from pressure-induced deformation during operation.
Commonly used in actuators, cylinders, and other fluid power assemblies on aircraft. Installation requires selecting the correct dash size and following component maintenance manual procedures for proper positioning and torque.
