ZINC CAPS - the common sense approach to low cost corrosion protection! Corrosion is the result of electrochemical activity/galvanic action. Scientific studies have proven that metals having a higher electrical potential will corrode and degrade in a typical corrosion cell, while protecting other metals having a slower electrical potential. Of all metals, Zinc has the highest electrical potential.  MARS Zinc Caps meet all MIL-A-18001J and ASTM B418-80 specifications.

Available in many sizes.
