Product Description
The MS28774-114 is a PTFE packing retainer (back-up ring) designed to support O-ring seals in high-pressure hydraulic systems. This scarf-cut retainer prevents seal extrusion by limiting radial expansion when pressure loads increase. Installed in standard seal glands per MIL-G-5514 specifications, it works alongside the O-ring to maintain system integrity in aircraft hydraulic actuators and fluid circuits.
Ensure the dash-114 size matches your O-ring and groove dimensions before assembly.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
