Product Description
The MS28775-225 is an acrylonitrile-butadiene rubber (NBR) O-ring packing manufactured to Military Standard MS28775 specifications. Molded at 75 Shore A hardness, this seal provides static and dynamic sealing in aircraft hydraulic systems. Commonly installed in Cleveland 30-146 brake assemblies, the O-ring fits into precision glands where it prevents fluid leakage under pressure and temperature cycling.
Installation requires lubrication with compatible system fluid and positioning per the aircraft maintenance manual or illustrated parts catalog. The MS28775-225 maintains pressure integrity in brake actuators and hydraulic control circuits across general and corporate aviation platforms.
