Restore insulation coverage and reduce condensation risk with this universal/spec-match Nu-Calgon Perma-Wrap Insulation Tape - 4218-W3. This closed-cell foam insulation tape wraps pipes, fittings, and refrigerant lines to help control sweating, heat transfer, and exposed insulation gaps.

4218-W3 is Nu-Calgon Perma-Wrap foam insulation tape, a universal/spec-match service wrap used on cold lines, chilled water piping, fittings, valves, and refrigerant tubing. This verified 2 inch x 30 foot roll with 1/8 inch thickness is commonly used when original insulation is damaged, cut back, or missing around a service area.

Compatibility: Cold water piping, chilled water lines, refrigerant lines, valves, tees, and fittings that need closed-cell insulation tape of the correct width and thickness.

Please confirm the tape width, length, material, thickness, and intended insulation or wrapping application before ordering.

Is it time to replace?

• Common Symptoms: Sweating pipes, exposed insulation gaps, dripping condensation, or service fittings left uncovered after a repair.
• Visible/Sensory Cues: Bare metal showing through, torn insulation, wet spots from pipe sweat, or tape that has compressed, split, or peeled away.

Pro Tip: Wrap the tape with a consistent overlap and avoid stretching it tight so the foam maintains its thickness around bends and fittings.
