Product Description
The MS20818-8D is an AN818/MS20818 tube coupling nut designed for 37° flared tubing in aircraft fluid systems. This steel nut works with an AN819 sleeve to clamp the flare against a fitting, creating a leak-free connection in hydraulic line assemblies. Installed where flared tubes join unions or ports, the coupling nut secures the connection through threaded engagement.
Proper installation requires pairing with the correct AN819 sleeve and torquing to specifications outlined in the aircraft maintenance manual. Conforms to AN standards for aerospace reliability.
