Refrigeration Technologies RT400P Viper Wetrag Heat Blocking Putty Jar (1), 12 oz.

Fantastic stuff!

With the crazy economy we find ourselves, my son and I ended up doing our own AC repair. We replaced our A-Coil and outside condenser unit with all the filters, fittings, etc. We also decided to use the solder with flux method as opposed to the silver rod brazing method. We were successful just before the hot muggy weather overtook our part of the country. We used this product to manage the heat transfer and avoid damaging other components in our high pressure line and liquid line. It worked well and was easy to apply and remove.

Great partner

Works awesome!

It works well but removing and reusing it is a bit dicey. The burned material is difficult to separate from the good portions so it doesn't stay in place well on next brazes. Even wetting my hands slightly to reform or regenerate the material it just gets harder to work with.

I've had the chance to use this a few times now brazing line sets for HVAC installation and it's held up well so far. I find it easier to use and is less in the way of what I'm working on then actual wet rags. The only downside is it can be a little messy to work with. Use a pair of disposable gloves when applying and it much easier to use

Viper Wet Rag (VWR) got me out of a jam. Had to heat water heater anode rod head in order to remove, without damaging tank glass lining and top cover paint. Molded VWR around anode rod, exposing only bolt head. Extended VWR around top of rod installation hole (top cover of water heater). Applied heat (propane) to anode rod bolt head (less than a minute). Gave rod head 2 short "braaps" with impact gun. Anode rod came out slicker than poop through a goose. Upon removal of VWR, surrounding foam insulation and water heater top cover paint were in pristine condition. Amazing product!!

Great product
