Your cart is empty.A must-have when brazing, soldering or welding. As a non-toxic, heat-absorbing putty, Hot Block will block direct and conductive heat transfer on all types of surfaces and metals, including: joints, valves, fittings, composite panels, rubber and plastics. Stops all transfer of heat down 3000º in half an inch. Wrap it around copper, aluminum and steel pipes. Perfect for stopping warping while welding on flat panels or body work.

I have been a plumber for over twenty years. And I remember the days when we didn't have this product. And how it limited doing service work. Now I can solder copper pipes and male and female adaptors tied into cpvc with just a few inches away. And it always works. Just make sure you use enough of it. I can sweat fittings back to back without heating up the next joint. This product is Amazing and a time saver!

Works well in the Auto Body industry also. Use it as a dam when welding to prevent warpage
