Fire Resistant Sleeve (sometimes spelled fire sleeve or fire-sleeve) Glass fibre sleeving treated with silicone is the perfect sleeve and jacket choice for protecting industrial hydraulic hoses and lines, pneumatic lines, fuel & oil lines, brake lines, wires and cables from exposure to high temperature, heat, flame, fire and pyro exposure. The extra thick special formulation of silicone rubber on our fire sleeve sheds molten metals, slag, welding splatter, electrical or grinding sparks and contamination. Fire sleeve also provides protection from ozone, UV, and abrasion.
The standard color of fire sleeve is red-oxide, but custom colors such as blue, grey, black, yellow and green are available; great for identifying hose and cable used when the sleeve is installed. Fire sleeve is the standard high-temperature and molten splash pyro protection jacket and sleeve for hose & cable.
