Nu-calgon NUCAL-4219-12 Foam Insulation Tape 2 in 30 Ft

Product Description

The NU-CALGON NUCAL-4219-12 is a closed cell elastomeric foam insulation tape designed to control condensation and heat loss on pipes, tubing, and fittings. Each roll measures 2 inches wide and 30 feet long, providing enough coverage for most residential and light commercial service calls. The closed cell construction resists moisture absorption, which is critical for maintaining thermal performance on cold lines. Licensed HVAC technicians, refrigeration mechanics, and plumbers install this tape on refrigerant suction lines, chilled water piping, cold water supply lines, and hot water distribution lines to maintain system efficiency and prevent surface sweating.

This insulation tape is suited for use on iron pipe, steel pipe, and copper tubing, as well as tees, valves, and fittings where pre-slit pipe insulation cannot conform easily. It is commonly applied during new installations and service work in residential and light commercial HVAC, plumbing, and refrigeration systems. The flexible foam conforms to irregular surfaces and curved fittings, making it practical for wrap applications where rigid insulation is impractical. Edges can be overlapped for added thickness or butted end-to-end depending on the application.

Key Features

• Closed cell elastomeric foam construction resists moisture absorption and condensation
• 2 inches wide and 30 feet per roll for efficient coverage on pipes and fittings
• Compatible with iron pipe, steel pipe, copper tubing, tees, valves, and fittings
• Suitable for both cold lines (chilled water, refrigerant) and hot water lines
• Flexible tape conforms to irregular shapes and fittings where rigid insulation cannot
• Edges can be overlapped or butted to suit the application

Compatibility

Designed for use on all standard pipe and tubing sizes including iron pipe, steel, and copper, as well as tees, valves, and fittings in cold water, chilled water, refrigerant, and hot water line applications.

Installation Notes

This tape is installed by HVAC technicians, refrigeration mechanics, and plumbers. Ensure pipe or tubing surfaces are clean and dry before application to achieve proper adhesion and thermal performance. On cold or refrigerant lines, allow the system to reach operating temperature before inspecting for condensation gaps. Follow applicable mechanical codes for insulation requirements on refrigerant suction lines and chilled water piping.
