The MS29513-018 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 components such as fittings, valves, housings, and actuator assemblies.

This O-ring is designed for consistent sealing performance under high pressure, vibration, and temperature cycling typical in aviation environments. 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 elastomer, offering strong resistance to aviation fluids, hydraulic oils, fuels, and environmental aging.
