K-FLEX® INSUL-TUBE® is a closed cell, flexible elastomeric tube foam insulation product used to retard heat gain and prevent condensation or frost formation on below-ambient applications. It can also be used with heat tracing tapes. K-FLEX® INSUL-TUBE® is black in color and is available in non-slit, 6’ length tube form in wall thicknesses of 3/8” up to 2” in diameter sizes ranging from 3/8” I.D. to 8” IPS (ID range is subject to variation depending on wall thickness). K-FLEX® INSUL-TUBE® is recommended for applications with service temperatures ranging from -297°F (-182°C) to +220°F (+104°C).
