Moroso’s -16AN to -20AN hose adapter is a black anodized transition fitting for AN plumbing systems. It allows installers to join -16AN and -20AN hose lines directly, which is useful when changing hose diameters within a high‑flow cooling or plumbing system while keeping AN‑standard connections and a consistent appearance thanks to the black anodized finish.
