Product Identity

Nu-Calgon 4296-50 is a 16 oz rubberized spray coating designed for HVAC repair and protection. It serves technicians and maintenance crews who need a flexible, white sealant for refrigeration and air conditioning components. The aerosol format allows quick application on site.

Compatibility Check

Verify that the system materials are compatible with a rubberized coating before spraying. Confirm the ambient temperature falls within the -10 to 250 degrees F application window. Ensure the surface is clean and dry for proper adhesion. The product is restricted in certain states; check local regulations before ordering.

Build Integration

The coating forms a protective barrier on ducts, pans and fittings, sealing small leaks and resisting vibration. It dries to touch in 20 to 30 minutes, reducing downtime during service calls. The 16 oz can covers multiple repair points, freeing technicians from carrying bulkier patch kits. No special tools are required beyond the aerosol nozzle.
