Harvey's Thread Seal Tape PTFE
Anode rod thread sealant and anti-seize tape
The mandatory thread sealant for anode rod installation. PTFE tape applied to the rod threads before installation prevents water weeping around the port and makes future rod removal significantly easier by preventing the thread seizure from mineral buildup that makes first-time removal so difficult on aging tanks. A $3 investment that saves a $150 plumber call next replacement cycle.
