Nu-calgon 4371-32 Thermo-trap Heat Absorbing Gel 32 Oz Spray Bottle

Product Description

The NU-CALGON 4371-32 Thermo-Trap Heat Absorbing Gel is a professional-grade thermal protection product designed to shield heat-sensitive components during soldering, brazing, and other high-temperature work. HVAC technicians, plumbers, and pipefitters rely on this type of heat absorbing gel to protect nearby fittings, valves, sensors, and materials that cannot tolerate direct or conducted heat during torch work. When brazing copper pipe or sweating fittings close to existing components, conducted heat can travel quickly through metal and damage seals, O-rings, plastic parts, or pre-installed valves. Applying Thermo-Trap gel creates a thermal barrier that absorbs and dissipates that heat before it can cause damage. The 4371-32 comes in a convenient 32 oz spray bottle, making it easy to apply the gel precisely where protection is needed without over-application. The translucent gel formula has a mild odor, making it suitable for use in occupied or enclosed spaces where strong chemical smells would be a concern. The specific gravity of 1 at 60 degrees Fahrenheit indicates the gel is water-based, and the pH rating of 9.5 means it is mildly alkaline, which is generally compatible with copper, brass, and other common plumbing and HVAC metals. The gel form clings to surfaces, including vertical pipes and fittings, without running off before heat is applied. Trade professionals working on HVAC systems, residential plumbing, commercial piping, refrigeration lines, and gas piping installations benefit from keeping a product like this on hand. It reduces callbacks and rework caused by heat damage during installation or repair. The spray bottle format allows quick, controlled dispensing in the field without additional tools.

• Translucent gel formula absorbs and dissipates heat during soldering and brazing operations
• 32 oz spray bottle provides precise, easy application on pipes, fittings, and heat-sensitive components

Product Highlights

The NU-CALGON 4371-32 Thermo-Trap Heat Absorbing Gel protects heat-sensitive components during torch work and is a practical addition to any HVAC or plumbing technician's toolkit. The spray bottle format and cling-gel consistency make application fast and efficient in the field.
