JXHK-GB-1262 is a precision-manufactured aerospace engine hydraulic actuation system sealing ring, compliant with AS9100D quality standards and aviation industry specifications, designed for large commercial aircraft engine actuation systems. It seals the connection positions of hydraulic components, preventing hydraulic fluid leakage, which is critical for maintaining stable hydraulic pressure, ensuring the accurate operation of engine adjustable components (such as VSV, VBV), and avoiding system failure that may affect engine performance.

Made from oil-resistant, pressure-resistant nitrile rubber with a reinforced metal O-ring insert, it withstands operating temperatures from -40°C to 180°C and hydraulic system pressures up to 5000 psi. Weighing 0.07kg with a precision-machined surface, it allows for fast replacement and tightness verification during actuation system MRO overhauls. It is a key component for engine actuation system stability.
