The MS29513-238 is an aerospace-standard O-ring (packing seal) used in aircraft hydraulic, fuel, pneumatic, and lubrication systems. It provides a reliable sealing interface between mating components such as fittings, valves, actuators, and pump housings, preventing fluid or gas leakage under pressure.

This seal is designed for consistent performance in demanding aviation environments, including exposure to vibration, temperature cycling, and high-pressure fluid systems. It is commonly used in both static sealing applications and assemblies with minor dynamic movement.

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