Insul-Tube Coil, 3/8" ID x 1/2" W x 1800 Linear FT, No Print, No Talc



K-FLEX® INSUL-TUBE® Coil is a flexible, closed-cell elastomeric insulation product used to conserve energy and prevent condensation on line sets and other extended length piping systems. Its extended length (250' to 2800' depending on the size) significantly reduces the number of butt joints and seams. 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® Coil is best applied to straight runs free of corners and bends. It is available with or without talc on the inner surface for effortless sliding in wall thicknesses ranging from 3/16" to 1".

K-FLEX® INSUL-TUBE® Coil 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® Coil is GREENGUARD® certifiedunder the Children and Schools classification, is approved through supervision by the Factory Mutual Research Corporation, and is 25/50-rated when tested to ASTM E 84 standards.
