This is the Mooresport Steering Rack Hardline Adapter. This adapter has been CNC machined out of the finest billet aluminum materials, and its intended purpose is to convert your 2015 steering rack to accept AN fittings. Mooresport also engineered this adapter to use o-rings along with a banjo bolt to secure their adapter block to the OEM steering rack. 

It will accept -6AN pressure line and -8AN return line, and it has been finished with a clear anodized coating to resist both oil and chemicals and to have extra protection against corrosion.
