Farwest Anode Caps seal and protect the critical connection between the lead wire and anode. The tight fitting, heat-shrinkable anode cap provides stress relief, moisture proofs and electrically insulates the end of the anode at the lead wire exit point. It is the ideal solution to the problem of premature system failure due to loss of the wire due to anode termination.
A unique, highly stabilized polyolefin material is used to mold the cap. During the manufacturing process, each cap is expanded to provide plenty of clearance for easy installation over the lead wire and the anode. A rubber based sealant, designed to adhere to anode materials and wire insulation, is uniformly coated on the inside of the cap.
During installation, a propane torch is used to heat the cap. As the temperature rises above 250°F, the sealant softens and the cap shrinks tightly to conform to the anode and lead wire. When cooled, the cap and sealant provide a durable and water tight encapsulation that will retain its flexibility and integrity over a wide range of temperatures.
Anode Caps are designed for anodes from 1" to 4" diameter. For high reliability in buried underwater cathodic protection systems, specify Farwest Anode Caps.
