The MS29513-243 is an aerospace-standard O-ring sealing element (packing) used in aircraft hydraulic, fuel, lubrication, and pneumatic systems. It provides a reliable, pressure-tight seal between mating components such as fittings, valves, pumps, and actuators.

This O-ring is designed to maintain sealing integrity under high pressure, vibration, and wide temperature variations typical in aviation environments. It is commonly used in both static and dynamic sealing applications depending on system design requirements.

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