Product Description
The MS28774-112 is a PTFE back-up ring conforming to MS28774 and SAE AS8791 specifications. This scarf-cut ring prevents O-ring extrusion in hydraulic and pneumatic system glands by providing structural support behind the primary elastomer seal. Installed in standard grooves per MIL-G-5514, the ring sits behind the sealing element in aircraft hydraulic actuators and fluid system components.
PTFE material withstands pressure cycling and temperature extremes common in aerospace fluid systems. Proper orientation during installation, as specified in system maintenance manuals, ensures effective extrusion resistance and seal longevity.
