The AN6289J4 is a stainless steel locknut designed to secure 1/4-inch OD flare-type tube assemblies in aircraft hydraulic systems. This tube fitting locknut prevents vibration-induced loosening of connections subject to pressure fluctuations and flight loads. Manufactured from Type 304 stainless steel for corrosion resistance in fuel, hydraulic, and pneumatic line environments.
Features 7/16-20 UNF threads for compatibility with standard AN flare fittings. Installation requires torquing to specifications outlined in the aircraft maintenance manual to ensure proper clamping force without over-tightening the flared connection.
