PURPLE Anodized -3 AN Tube Nut, 3/16"

 Our AN Fittings are carefully machined from 6061-T6 Billet Aluminum and finished with our proprietary polish and anodizing process. This anodizing process prevents galling on the threaded surfaces, adds protection against corrosion and wear, and gives them their distinctive color. Traditionally, AN Fittings are produced in a red/blue color combination, paying homage to their origins in army and navy applications. However, we like to think outside the box - bringing you this nod to our friend Todd Clark, in the Purple 00 SK Light.
