INSUL-Lock® Pre-Slit is a flexible, closed-cell elastomeric pipe 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 protects against moisture penetration in applications within a -40F to +220F temperature range.
INSUL-LOCK® 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”. INSUL-LOCK® is pre-slit, non-porous, non-fibrous and resists mold, fungal and bacterial growth. For added protection, it is protected with an EPA-approved antimicrobial agent.
INSUL-LOCK® 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.
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.
