RectorSeal has introduced Cool Braze, the reusable heat absorption putty for the HVAC/R, plumbing, and welding markets. Cool Braze putty blocks soldering, brazing, and welding heat conduction and sparks from damaging nearby soldered fitting joints, piping, and valves. It can be used on a variety of surfaces and metals, including composite panels, rubber, and plastics. Cool Braze is especially useful for protecting reversing valves, ball valves, and TXV components. Cool Braze was developed to completely stop the transfer of heat up to 3000°F (1,649°C). It is effective when using MAPP gas, Oxy-Acetylene, MIG, TIG, Arc, and Propane torches.
