Product Description
The 491-082 is a union fitting that joins two flared tube ends in-line for aircraft fluid systems. This connector uses 37-degree aviation flares with a central sleeve and nut assembly to create leak-free joints in hydraulic, fuel, and pneumatic lines. Constructed from aluminum or steel per AN815 specifications, the union maintains system integrity under pressure and vibration.
Installation requires matching the correct sleeve size, applying proper torque per FAA AC 43.13-1B guidelines, and verifying compatibility with your aircraft's maintenance documentation before assembly.
