Product Description
The ms28774-327 is a PTFE packing retainer designed to support O-rings in pressurized glands and prevent extrusion. This single-turn, scarf-cut backup ring is commonly used in aircraft hydraulic actuators where fluid pressure forces seals outward. The retainer holds the O-ring concentrically within the gland cavity, maintaining seal integrity during operation.
Installation requires orienting the scarf joint per the aircraft maintenance manual and verifying dimensions against SAE AS8791/MS28774 specifications before return to service.
