Product Description
The MS28782-7 is a PTFE backup ring designed to support O-rings in high-pressure hydraulic and fuel system glands. This packing component resists extrusion, preventing seal failure under extreme pressure conditions common in aircraft landing gear hydraulics. Install the backup ring adjacent to the O-ring per MS28782/SAE AS8791 specifications and maintenance documentation.
Proper sizing and positioning ensure optimal seal reliability and system integrity. Verify compatibility with your aircraft's Illustrated Parts Catalog before installation.
