  • Product Description
    ThermFlex™ 1226 is a heat-treated sleeving that provides superior protection against conducted and convected heat. Constructed of knitted fiberglass, ThermFlex 1226 is used to protect components in high temperature areas.

    Due to its knitted construction, ThermFlex 1226 is easy to install with its excellent flexibility and expandability characteristics. The ends of the sleeve are treated. This process avoids the ends from fraying and particles from spreading. It also provides superior insulation to components that must maintain elevated temperatures to maximize performance efficiency.

    ThermFlex 1226 is also used on fuel and hydraulic lines, cables and hoses proximity to engines and exhaust systems.
