Product Description

The c04b-a is a nitrile rubber O-ring designed for propeller constant-speed governor and hub assemblies. This seal maintains engine-oil pressure within the propeller system, preventing leaks that would compromise pitch control mechanisms. Sized to AS568 standards and manufactured per MS28775 specifications for oil-resistant applications, the O-ring provides static sealing in governor cavities and hub interfaces.

Installation requires compatible lubricant application and torque verification per the aircraft maintenance manual and illustrated parts catalog.

Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
