The MS28774-236 is a PTFE backup ring designed to prevent O-ring extrusion in high-pressure hydraulic and pneumatic systems. This retainer installs in the gland adjacent to the primary sealing O-ring, creating an anti-extrusion barrier that protects against pressure-induced failure. Conforming to SAE AS8791 scarf-cut ring specifications, the MS28774-236 maintains seal integrity in aircraft hydraulic components operating under demanding pressure cycles.
Installation requires proper orientation per maintenance documentation and verification against NSN 5330-00-582-1543 specifications.
