K-FLEX INSUL-TUBE is widely used for its cold weather flexibility, durable skin surface, exacting manufacturing tolerances and lasting performance. It is available in 6’ lengths in a range of wall thicknesses ranging from 3/8″ to 2” and is 25/50-rated, according to ASTM E-84 standards for surface burning characteristics of building materials, up to 2″ wall thickness.
K-FLEX INSUL-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 INSUL-TUBE is GREENGUARD certified under the Children and Schools classification and is approved through supervision by the Factory Mutual Research Corporation.
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 75F and wvt of .03 perm-in) that protect against moisture penetration in applications within a -297°F to 220°F temperature range.
