Product Description


K-FLEX PE is recommended for applications with service temperatures ranging from -200°F (-129°C) to +200°F (93°C). The product is used to retard heat gain or loss and prevent condensation on below-ambient applications including cold water plumbing, chilled water, and industrial process lines, among others. It also can be used to prolong the time to freezing and can be used with heat tracing tapes. It also retards heat loss from medium hot systems, including hot water plumbing. K-FLEX® PE is used in both residential and commercial applications.
