Product Description
The MS21921K8 is a tube coupling nut for flareless aircraft tubing, conforming to Military Standard MS21921 (superseded by SAE AS21921). This steel nut works with a compression sleeve to create a leak-tight joint on hydraulic and pneumatic line fittings. The nut threads onto the fitting body, clamping the sleeve against the tube to form a secure seal without flaring the tube end.
Common in aircraft hydraulic systems, fuel lines, and pneumatic circuits. Install with matching MS/AS sleeve and fitting components, torquing per aircraft maintenance manual specifications to ensure proper seal integrity.
