K-FLEX® INSUL-TUBE® Pre-Slit 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 -297F to +220F temperature range.
K-FLEX® INSUL-TUBE® Pre-Slit is widely used in the HVAC/R and plumbing markets for its cold weather flexibility, durable skin surface, exacting manufacturing tolerances and lasting performance. It is pre-slit to reduce installation time and is available in 6' lengths in wall thicknesses ranging from 3/8” to 1-1/2”.
K-FLEX® INSUL-TUBE® Pre-Slit 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® INSUL-TUBE® Pre-Slit is GREENGUARD® certified under the Children and Schools certification, is approved through supervision by the Factory Mutual Research Corporation, and is 25/50-rated when tested to ASTM E 84 standards.
