MEETOOT 6AN Male to Male Flare Union Straight Connector - Black Aluminum Fuel Hose Adapter, 9/16-18 UNF 37° Interface, for Fuel/Oil/Coolant Systems, 2-Pack

This 6AN male to male straight flare union connector is a basic connecting component in fuel system and fluid line modifications. Both ends are equipped with standard 6AN (9/16-18 UNF) male threads and 37° flare sealing surfaces, which tightly engage with various AN6 female connectors and hose ends to form a reliable high-pressure seal. The 6061-T6 aluminum alloy provides excellent mechanical strength and rust resistance while reducing weight, and the black anodized surface enhances wear resistance and appearance. It is widely used for line extension and connection in automotive fuel systems (gasoline/diesel/E85), oil cooling circuits, transmission cooling, hydraulic systems, and compressed air lines. Whether in track racing or daily street modifications, it ensures stable fluid transmission.
