Zinc Anode 20mm, 25mm and 32 mm (Free Postage)

 This Zinc anode with stainless steel 316 tube. It is for protecting pump body against corrosion.

The Zinc anode is used to help deter corrosion in the submerged pump system. This sacrificial anode with stainless steel 316 tube will redirect the corrosion from your pump to itself via differences in voltage potential. This means the anode will be consumed in corrosion in preference to the pump, increasing the lifespan of the pump.

There are three different anode sizes which are 3/4"(20mm), 1"(25mm) and 1 1/4" (32mm).
