Foam Tube Insulation Details

Rubber Foam Insulation Tube is used to retard heat gain and control condensation drip from chilled-water and refrigeration systems. It also efficiently reduces heat flow for hot-water plumbing and liquid-heating and dual-temperature piping. The recommended temperature usage range for Rubber Foam Insulation Tube is -297°F to +220°F(-183°C to +105°C).

For use on cold pipes, Rubber Foam Insulation Tube thicknesses have been calculated to control condensation on the insulation outer surface, as shown in the table of thickness recommendations.
