Aeroflex Everseal Cork Tape is specially designed for all types of climates. It insulates cold pipes for all kinds of air conditioners used in cars and homes, freezers and refrigerators. Helps stop condensation problems. Ideal for retarding heat gained in cold pipes and preventing heat loss in hot pipes. Aeroflex Everseal Insulation Tape is an effective sound dampening material and can also be used for gasketing purposes. Aeroflex Everseal Insulation Tape sticks to all kinds of dry metals, It seals tightly without drying. It is flexible and will not shrink or melt within the service temperature of – 29c to 93c.
