Product Description
The AN816-3D is an aluminum straight nipple adapter that joins 37° flared tubing to pipe-thread ports in aircraft fluid systems. This AN standard component connects flared aluminum fuel lines to NPT (National Pipe Thread) ports commonly found on engine fuel system components. Installation requires an AN818 nut and AN819 sleeve, torqued per FAA AC 43.13-1B specifications.
The adapter maintains pressure integrity in fuel delivery circuits on general aviation and corporate aircraft, where reliable tube-to-port connections prevent leaks during operation.
