MS20819-3J Sleeve Flared Tube Fitting is a military standard aircraft fitting component designed to provide reliable support and proper load distribution for flared tube connections used in aerospace fluid systems. The sleeve is installed between the tube flare and coupling nut, helping maintain a secure connection while reducing the risk of tube flare damage during installation and service.

Manufactured in accordance with the MS20819 specification, this precision-machined sleeve is designed for use with compatible flared tube fittings in aircraft hydraulic, fuel, oil, lubrication, and pneumatic systems. Its accurate dimensions ensure proper alignment between mating components and support dependable sealing performance in environments exposed to vibration, pressure changes, and temperature variations.

The sleeve provides mechanical support to the flared tube connection by distributing clamping forces evenly across the assembly. This helps maintain system integrity and contributes to reliable fluid transfer performance throughout the aircraft. Proper installation with the correct tubing size and compatible fittings is essential for achieving the intended sealing characteristics.

During maintenance inspections, the sleeve should be checked for corrosion, deformation, cracking, or signs of wear. Replacement of damaged components helps maintain the reliability and safety of aircraft fluid system connections.
