Contractor-friendly 4″ x 4″ protective cover for exothermically welded anode connections. Requires application of adhesive primer.

thermOwelds® NEW thermOcap® PC is a 4″ x 4″ prefabricated assembly designed as a protective cover for exothermically welded leads to pipes and tanks. When pressed by hand into position over the anode lead wire weld, it forms a thick, highly resistant electrical insulation seal over the weld, the end of the lead wire and the surrounding area of the pipe or tank.

As opposed to the thermOcap, the thermoOcap PC is pre-primed with an elastomeric adhesive and does not require a spray primer.

  • Pre-primed for 1-step application.
  • Elongated wire inlet allows the cap to conform easier to the pipe
  • Outer shell designed to prevent crushing
  • Butyl rubber filled dome
  • Easier field application
  • Contractor friendly
