Key Features

• Reusable up to 40 times – long-lasting value for frequent jobs
• Withstands over 2000°F – extreme temperature resistance
• Protects against direct and conductive heat
• Built-in indicator dye fades as the rag wears out, so you know when to replace it

How It Works

Simply wet the VIPER WETRAG, wring out the excess water, and place it around the area to be protected during brazing or soldering. It forms a thermal barrier that absorbs heat and blocks conduction to nearby sensitive parts. Reuse after cooling down and rewetting as needed.

Applications

• Brazing and soldering in HVAC systems
• Refrigeration line repairs near valves or TXVs
• Protecting electrical components from heat
• Servicing rooftop units and confined repair areas
