K-Flex Insul tube is a flexible, closed cell elastomeric tube insulation product used to conserve energy and prevent condensation on piping applications. The product's closed cell structure creates exceptional thermal properties (k-value of 0.245 at 75 deg F and wvt of 0.03 perm-in) that protect against moisture penetration in applications within a -297 to 220 deg F temperature range. K-Flex Insul tube is widely used for its cold weather flexibility, durable skin surface, exacting manufacturing tolerances and lasting performance.
