Anode cap seals and protects the critical connection between lead wire and anode. The tight fitting, heat shrinkable anode cap provides stress relief, moisture proofing and electrically insulates the end of the anode at the lead wire exit point. It is the ideal solution to prevent premature system failure due to loss of the wire to anode termination.
