5″ Flexsul-Seal Pex Insulation High R-Value Thermal Insulation

Product Description

Flexsul-Seal is an elastomeric thermal insulation used to retard heat loss in hot water plumbing and dual hot waterline systems. The Flexsul-Seal system is designed to trap dead air, within an expanded closed cell structure, thus increasing its total R-Value and reducing heat loss in cold underground burial.

Typical Applications

Outdoor furnaces and boilers
