Hot Block® is a pliable, formable putty-textured packing for protecting nearby HVAC/R and plumbing pipe, valves, components and surfaces from damaging heat conduction, transfer and sparks during jobsite brazing, soldering and welding for commercial refrigeration, air-conditioning and plumbing systems. While many heat blocking putties are one time use, hot Block® is reusable dozens of times, because its proprietary formulation is easily rejuvenated with a spritz of water before storing back into its 8 oz (metric) plastic jar. Hot Block® separates surrounding areas from potentially conductive brazing/soldering temperatures of 850 deg F and reduces them by up to 90%. It also doesn’t degrade from welding temperatures of up to 3000 deg F. Besides absorbing heat, hot Block® can also prevent nearby drywall or wood from igniting, existing fitting joints from unsoldering or flange bolt/nut threads, valves and sensitive equipment from residual spark damage.
