What We Do

MIL-A-8625, Duplex Seal

Hillock Anodizing’s extensive knowledge of sealing technologies allows for adherence to most customer or military specification seal requirements. A common term used to describe multiple seals on the same part is Duplex Sealing. MIL-A-8625 lists the Duplex Seal as nickel acetate with sodium dichromate or nickel acetate seal first followed by sodium dichromate seal second. Hillock Anodizing offers both sealing methods and frequently performs the Duplex Seal for Military contracts. The black dye used for this process is not affected by the sealing process so the parts aesthetics are maintained while increasing the corrosion resistance.
