Product Description
The MS28783-5 is a PTFE back-up ring designed to work alongside O-ring seals in aircraft hydraulic systems.

Conforming to MS28783 and AS8791/MIL-R-8791 specifications, the dash-5 size corresponds to AS568-227 dimensions.
Installation requires positioning the scarf joint per maintenance manual guidance and verifying proper fit within the gland assembly. Commonly used in dynamic and static sealing applications throughout pressurized fluid systems.
