MS28782-32 Aircraft Backup Retainer Rings – NEW (Set of 2)

This listing is for two (2) new MS28782-32 backup retainer rings, commonly used in aircraft hydraulic sealing systems.

MS28782 backup rings are designed to support and protect O-rings in high-pressure hydraulic applications. The ring prevents extrusion of the O-ring under pressure and helps maintain reliable sealing performance within hydraulic components.

These rings are manufactured from PTFE / Teflon type polymer, providing excellent chemical resistance, low friction characteristics, and long service life in demanding aviation environments.

MS28782 series backup rings are military specification aircraft hardware used across a wide range of general aviation and military aircraft including applications on Cessna, Piper, Beechcraft, and other aircraft hydraulic assemblies.

The split ring design allows installation into sealed assemblies without removing surrounding components.
