956A8018G02 is a precision aerospace component, compliant with AS9100D quality standards and FAA/EASA regulations, designed for the hydraulic systems of large commercial aircraft.

It acts as a hydraulic check valve seal ring, forming a reliable, airtight seal between the check valve's valve disc and valve seat. This seal prevents reverse hydraulic fluid flow, maintaining the one-way fluid movement that is essential for the normal operation of hydraulic components such as flight controls, landing gear, and brake systems, avoiding pressure loss or component malfunction that would threaten flight safety.

Made from oil-resistant, high-temperature fluorosilicone rubber, it can withstand temperatures from -40°C to 240°C and long-term contact with aviation hydraulic fluids. Weighing 0.07kg, it enables quick replacement during MRO, and is a critical component for hydraulic system stability.
