ArmaFlex Insulation Tape

Pressure sensitive foam tape for easy insulation of pipes and fittings

It is used to retard heat gain and control condensation drip on domestic cold-water, chilled-water, and other cold piping and fittings, and to reduce heat loss when applied to hot-water lines that operate up to 180°F (82°C). It is perfectly suited for insulating short lengths of pipe and fittings in congested or hard-to-reach areas.

AP ArmaFlex 2” wide insulation tape may also be used in conjunction with AP ArmaFlex pipe and sheet insulation.


AP/ArmaFlex Insulation Tape provides a fast, easy method of insulating pipes and fittings.
