The C-048-B O-Ring is an MT-Propeller hub sealing component used in aircraft variable-pitch propeller assemblies. It provides a critical pressure and oil-tight seal within the propeller hub, helping maintain proper hydraulic pressure for blade pitch control and preventing oil leakage during operation.

This O-ring is typically pre-installed in MT composite propellers at assembly and is part of the propeller’s internal sealing system. It is designed to operate in a high-vibration, high-RPM environment and must withstand exposure to engine oil, temperature variations, and centrifugal forces.

Manufactured to MT-Propeller specifications, the C-048-B is made from high-performance elastomer material (typically fluorocarbon/Viton-type or equivalent aviation-grade compound), ensuring long service life and stable sealing performance in demanding aviation conditions.
