Rector Seal Cool Braze™

Reusable heat absorption putty

Originally published: 4/10/2023

RectorSeal LLC., a leading manufacturer of quality HVAC/R and plumbing accessories, introduced today Cool Braze, the reusable heat absorption putty for the HVAC/R, plumbing, and welding markets. RectorSeal is a wholly owned subsidiary of CSW Industrials, Inc. [NASDAQ: CSWI]. 

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.

While many heat-blocking putties are for one-time use, Cool Braze can be reused multiple times. Its formulation is easily rejuvenated with a spritz of water before being stored back in its convenient plastic jar. Cool Braze is non-toxic, non-flammable, and odor-free. 

Cool Braze offers several advantages compared to using alternative methods to prevent heat transfer. When properly used, it protects copper, aluminum, steel, and all other pipe and component materials from discoloration, warpage, and distortion, even on thin metal. Cool Braze can be used to hold, align, and jig parts for brazing, soldering, or welding. In addition to absorbing heat, Cool Braze can prevent nearby drywall or wood from igniting, preventing existing fitting joints from unsoldering, and offers residual spark damage to flange bolt/nut threads, valves, and other heat-sensitive equipment.
