C32017-67 is a precision aviation maintenance component compliant with AS9100D standards and FAA/EASA regulations, engineered for sealing and connection in aircraft hydraulic pipeline systems during ground MRO and assembly. Fabricated from high-strength corrosion-resistant alloy steel with oil-proof plating, it withstands extreme temperatures from -55℃ to 200℃, resisting hydraulic fluid erosion and high-pressure impacts without leakage or deformation. Its precision-machined interface ensures tight, stable fitting with matching pipeline parts, avoiding loosening risks during flight. Compact and easy to install, it adapts to confined hydraulic compartments, streamlines maintenance workflows, cuts ground downtime, and serves as an indispensable part for aircraft operational reliability and flight safety.
