Product Description
The AN821-5D is a 90-degree, 37-degree flared tube elbow for aircraft hydraulic systems. This aluminum alloy fitting connects 5/16-inch diameter tubes at right angles, enabling efficient line routing in confined engine and fuselage spaces. Installation requires pairing with AN818 nut and AN819 sleeve components, torqued per aircraft maintenance manual specifications.
The AN821 standard defines the flare configuration and connection geometry. Now superseded by SAE AS1034, though AN821-5D remains in service across general and corporate aviation fleets for hydraulic circuit modifications and repairs.
