SLEEVE (P/N 4730-00-289-8622) - New Surplus

The MS21922-12 is a steel tube fitting clinch sleeve designed for 24° cone flareless connections in aircraft hydraulic systems. This sleeve works with a coupling nut to create a secure, bite-type seal around rigid tubing without requiring flaring. During installation, the nut compresses the sleeve onto the tube, forming a leak-free connection that withstands hydraulic pressure and vibration.

Assembly and service follow SAE AS18280 standards and applicable aircraft maintenance manual torque specifications. Commonly used in hydraulic circuit repairs and new installations across general and commercial aviation.
