This is an aluminum -16AN flare female to 16AN ORB male fitting. This fitting was not available anywhere on the internet that I could find so I designed my own. You would typically use this on large fuel pump inlet or waterpump. Comes with jam nut and oring.

Installation

Just like any other fitting, however because it is not a swivel fitting there are some extra room for the jam nut threads so you can clock it however you want then tighten the jam nut. Make sure the oring is in the proper position to make the seal against the porn and jam nut (not on the threads).
