About Selecting Thermal Insulation

Flexible Rubber Foam Pipe Insulation

Soft and easy to install, this insulation restricts absorption of water, air, and gas. It is often used on cold and hot water lines and refrigeration lines. Seal with contact adhesive (sold separately). To use outdoors, coat in acrylic paint.

Slit tubes have an adhesive strip closure.

Tear-Resistant Silicone Foam Pipe Insulation

Temperature Range: -65° to 500° F
Heat Flow Rate: 0.39 Btu @ 75° F
Density: 45 lbs./cu. ft.
Color: Black

Even at high temperatures, these tubes remain flexible to stretch over components without tearing. They restrict absorption of water, air, and gas and are typically used on hot and cold water lines and electrical components.
