    High Temperature Cable Sleeving Products

    Silicone Fiberglass Ultra-Sleeve High Temperature Sleeving with & without Hook & Loop Closure

    Thermo-Trex® Silicone Fiberglass Ultra-Sleeve High Temperature Sleeving is a protective sleeve that is ideal for harsh environments of flash heat or flame, moisture, chemicals or mechanical abuse. Our high-temperature sleeving is made up of an ultra-heavy grade fiberglass base fabric and coated with a heavy layer of specially compounded silicone rubber to resist temperatures up to 260°C continuously. With each heat-resistant sleeve we produce, you can expect your cables to have a longer life in high-heat if they are regularly exposed to molten splash, flash heat and flame. Also available with Hook and Loop closure for easy installation.
