Insultherm® Ultra Flex® Flexible Fiberglass Sleeving

High Performance Thermal Protection


insultherm ultra flexx beauty
BRAIDED FIBERGLASS PROTECTS UP TO 1,200°F

Ultra Flex® fiberglass sleeving is ideal for the protection of wires and hoses exposed to the heat generated from high performance engine and exhaust components. The heat treated sleeving cuts with scissors and is compatible with most bonding and saturation systems. The 1/64" wall thickness provides economy, protection and light weight in any application. Ultra Flex® expands slightly, allowing it to slide easily over wires and follow curves and contours without bonding.When greater protection levels are required, Our Ultra Flex® Pro Fiberglass sleeving is an ideal heavy duty alternative.
