Description

Zinc Anode Caps

Cor-Cap® Zinc Anode Cap, is a sacrificial zinc nut (Sac Nut or Zinc Nut) or galvanic anode which is utilized for Cathodic Protection of flanges, mechanical fittings and gland/ring assemblies installed on metallic (i.e., steel) joints for direct burial. To increase the amount of Cathodic Protection and/or the design life of the installation, multiple Cor-Cap®‘s can be installed on each bolt. Cor-Cap®‘s are not recommended for use on stainless steel nuts and bolts as this will accelerate the rate of corrosion activity on the assemblies.

Cor-Cap® Zinc Anode Caps are manufactured to meet ASTM Standard B418 (latest revision), Type II and can be purchased in several sizes, including but not limited to:

  • UNC ½” Threaded, Zinc Anode Cap
  • UNC ⅝” Threaded, Zinc Anode Cap
