The Russell -6AN to 5/8-18 adapter provides a blue-anodized transition between AN fittings and 5/8-18 inverted flare female ports. Precision machined from steel, it ensures precise thread engagement and a positive seal at maximum operating pressures, letting AN hose ends be connected cleanly to pumps or filters that use the larger inverted flare thread standard.
