Corrosion Grenade® Corrosion Grenade, 3/4 in, Composition: 99.99% Zinc, Silver

• The corrosion grenade unit protects metal parts by acting as a "sacrificial anode"
• It corrodes instead of expensive A/C parts like aluminum fins, copper piping, and galvanized steel
• The marine and plumbing industries have been using "sacrificial anodes" for decades to protect other functional parts from galvanic corrosion
• By adding the Corrosion Grenade to the assembly, the zinc becomes the weakest metal and therefore, is the one that corrodes
