Design Engineering Ultra Sheath MA is designed to provide the ultimate protection against heat for hoses, wires or cables. Ultra Sheath MA is constructed using a process which impregnates molten aluminium into the core fabric which allows it to withstand sustained direct heat up to 593° C (1100° F).Extreme heat protection for wiring or hosesEasily trimmed to lengthUltra lightweight. Up to 40% lighter than other heat sleevesProvides direct heat protection up to 593° C (1100° F)Easily fitted by sliding over the hose or cable and can be trimmed to length with a sharp knife. Ultra Sheath is also very flexible so can be used on tight bends.
