Company: RectorSeal® LLC

Product: Hot Block®

Description: This pliable, formable, putty-textured packing protects nearby HVACR and plumbing pipe, valves, components, and surfaces from damaging heat conduction, heat transfer, and sparks during job site brazing, soldering, and welding for commercial refrigeration, air conditioning, and plumbing systems. It is reusable dozens of times because its proprietary formulation is easily rejuvenated with a spritz of water before storing in its 8-ounce plastic jar. Hot Block separates surrounding areas from potentially conductive brazing/soldering temperatures of 850°F (454°C) and reduces them by up to 90 percent. It also doesn’t degrade from welding temperatures of up to 3,000°F (1,649°C). Besides absorbing heat, Hot Block can also prevent nearby drywall or wood from igniting; existing fitting joints from unsoldering; or residual spark damage to flange bolt/nut threads, valves, and sensitive equipment.
