Product Description
The MS28775-028 is a preformed elastomeric O-ring for static sealing in aircraft hydraulic and pneumatic systems. This seal conforms to Military Standard MS28775 specifications and seats in standard glands to prevent fluid leakage at fittings and component interfaces. Commonly installed in MIL-H-5606 hydraulic pumps, valves, and actuators where reliable static sealing is required.
Proper installation requires matching gland dimensions per MS28775 standards and applying appropriate lubricant before assembly. The seal maintains pressure integrity across temperature ranges typical in general aviation and commercial aircraft fluid systems.
