K-Flex - LS 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 75F and wvt of 0.03 perm-in) that protect against moisture penetration in applications within a -297°F to +220°F temperature range.

K-FLEX® LS Tube is widely used in the commercial and industrial markets for its cold weather flexibility, durable skin surface, exacting manufacturing tolerances and lasting performance. Available in 6' lengths in wall thicknesses ranging from 3/8" to 2", K-FLEX® LS Tube is non-porous, non-fibrous and resists mold, fungal and bacterial growth. For added protection, it is protected with an EPA-approved antimicrobial agent.

K-FLEX® LS Tube is GREENGUARD® certified under the Children and Schools classification, is approved through supervision by the Factory Mutual Research Corporation, and is 25/50-rated up to 2" wall thickness when tested to ASTM E 84 standards.
