This aluminum fitting is designed to adapt your rubber hose to a male AN fitting. One end has a 5/16" OD barb to accept a 5/16" or 8mm ID hose. The other end has a female 6AN swivel nut to fit any standard 6AN male fitting. The two-piece design allows the female nut to be tightened down without turning the hose. The straight fitting has a silver anodized aluminum finish that looks great with an aluminum radiator. Sold individually.
Note: The barb on this fitting is very mild. It will require a hose clamp (sold separately) for sealing and retention. Not for use with 6AN braided hose.
