ArmaFlex insulation tape is a black, closed-cell, mold-resistant, elastomeric thermal insulation tape for insulating pipes and fittings. This self-adhering foam tape is a quick and easy method to use for insulating due to it's pressure-sensitivity and flexibility. Ideal for use when wrapping hot or cold pipes, tubing, and fittings due to its ability to prevent condensation, heat loss, and formation of frost on chilled water tubing and refrigeration lines.
