FKM 2X Hi-Temp Fluoroelastomer Heat Shrink

Very flexible at high and low temperatures without cracking. Made from modified fluoroelastomer, FKM is used for applications at elevated temperatures, has superior chemical and solvent resistant properties. It reliably protects wires, solder joints, terminals, connectors and components from most industrial fluids, solvents and chemicals.
