The MS29513-123 is an aerospace-standard O-ring seal (packing element) used in aircraft hydraulic, fuel, lubrication, and pneumatic systems. It provides a dependable sealing interface between mating components such as fittings, valves, pumps, and actuator housings, ensuring leak-free operation under pressure.

This O-ring is designed to perform in demanding aviation environments where it is exposed to vibration, pressure cycling, and wide temperature variations. It is suitable for both static sealing applications and light dynamic movement depending on system design.

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