Product Description
The MS28782-30 is a PTFE backup ring designed to prevent O-ring extrusion in pressurized hydraulic seals. This ring installs adjacent to the O-ring in aircraft actuator and valve grooves, supporting the seal under high pressure conditions. Backup rings are essential components in hydraulic systems where pressure differentials could otherwise force the O-ring out of its groove.
The MS28782 military standard specifies dimensions and material properties for aerospace applications. Verify groove geometry and backup ring eligibility in the aircraft maintenance manual or Illustrated Parts Catalog before installation to ensure proper fit and seal integrity.
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.
