This aluminum fitting is designed to adapt your rubber hose to a male AN fitting. One end has a 1.5" OD barb to accept a 1 1/2" ID hose. The other end has a female 20AN swivel nut to fit any standard 20AN (1 5/8-12 UNF thread, 37° JIC flare) 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 1: The barb on this fitting is very mild. It will require a hose clamp (sold separately) for sealing and retention. Not for use with 20AN braided hose.
Note 2: The 20AN size was developed to be the equivalent of 1.25" OD tubing. 20AN fittings are more commonly used with 1 1/4" ID hose.
