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.
INSUL-TUBE® 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 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.
These rubber pipe insulation products are non-porous, non-fibrous and resist mold, fungal and bacterial growth. For added protection, they are protected with an EPA-approved antimicrobial agent.
INSUL-TUBE® is also GREENGUARD® certified under the Children and Schools classification and is approved through supervision by the Factory Mutual Research Corporation.
Rubber Pipe Insulation is also called Hydronic Pipe Insulation in different specs and was commonly referred to as Rubatex in the past.
Additional Jacketing is recommended for outdoor use: PVC and Metal Outdoor Jacket

Sizing for rubber pipe insulation is done by Copper Pipe Outside Diameter. For example, the correct size to order for 1/2" Copper Pipe is 5/8" (the O.D. of a 1/2" Copper Pipe). Please see sizing chart for Iron Pipe Size (IPS) conversions.
