Product Description

The AN819-3D is an aluminum sleeve for 37° flared tube fittings designed for 3/16-inch tubing. This component sits behind the flare and works with an AN818 nut to support and seal the connection. The sleeve prevents flare collapse under torque during installation and operation.

Used in aircraft fuel lines and hydraulic systems where reliable leak-free connections are critical. Install on properly flared 3/16-inch tubing per aircraft maintenance manual specifications. Equivalent to MS20819 and SAE AS5176 standards.
