RectorSeal Becomes Exclusive Distributor for Hot Block, the Reusable Heat Absorption Putty

RectorSeal® LLC, a manufacturer and distributor of quality HVAC/R and plumbing products, is now the exclusive U.S. and Canadian distributor of Hot Block®*, the reusable heat absorption putty for the HVAC/R, plumbing and welding markets.

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-ounce (metric) 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 flange bolt/nut threads, valves and sensitive equipment from residual spark damage.

It is available in 8-ounce (0.2-liter) plastic jars from HVAC and plumbing wholesale distributors. The jar includes a four-color label with instructions.

Other Hot Block advantages are:

  • Price is less than the cost to replace an expensive component left unprotected during a nearby brazing;
  • Outperforms and is more convenient than the industry standard of wet rags;
  • Protects copper, aluminum, steel and all other pipe and component materials;
  • Can be used with all types of brazing, soldering and welding gasses;
  • Available to RectorSeal authorized wholesalers in 12-jar cases.
