The DeatschWerks 6AN male flare to 5/16-inch hardline compression adapter transitions from a 6AN flare fitting to a 5/16-inch hardline compression connection and includes one olive insert, finished in anodized matte black. It lets you join soft AN flare lines to hardline compression runs. Sized for 6AN flare and 5/16-inch hardline, the supplied olive insert supports a proper compression seal where hard tubing meets AN fittings.
