Earl's Ano-Tuff AN to NPT Adapter Fittings

Product images may differ from actual product appearance.

The Earl's Ano-Tuff AN to NPT Adapter Fittings are precision machined from aluminum with a distinctive, bright dipped black, Military Spec hard anodizing. The recently developed hard anodizing process adds superior wear and corrosion resistance to aluminum at a reasonable price. The Ano-Tuff coating penetrates the aluminum creating a surface that last twice as long as traditional anodized coatings! Made in the USA!
