The MS29513-212 is an aerospace-standard O-ring sealing element (packing) used in aircraft hydraulic, fuel, lubrication, and pneumatic systems. It provides a reliable leak-proof seal between mating surfaces such as fittings, valves, pumps, and actuator housings.

This O-ring is designed to maintain sealing performance under high pressure, vibration, and wide temperature fluctuations typical in aviation service conditions. It is commonly used in both static and lightly dynamic sealing applications where consistent pressure integrity is required.

Manufactured to MS specifications, it is typically made from FKM (Viton-type) or equivalent aerospace elastomer, offering strong resistance to hydraulic fluids, aviation fuels, oils, and environmental exposure.
