Fire Sleeve Specialists – Certified Protection You Can Trust

Date: 12/09/25

Fire sleeve is an indispensable product that adds a critical layer of protection for pipes and hoses, cables and wires. The woven E-glass fibre yarn, coated with a high-grade, fire-resistant silicone elastomer rubber, delivers continuous protection at temperatures up to 260°C and molten splash protection at up to 1200°C.

Even direct flame will struggle to get through your fire sleeves, as the top silicone layer melts when exposed to flame, forming a protective layer of silicone dioxide. And as well as resisting fire, fire sleeve also resists a wide range of other environmental contaminants, protecting your equipment from leaks, spills and splashes, including oils, hydraulic fluids, acids and alkalis.

If you missed the chance to install the peace of mind protection of fire sleeve during installation, don’t worry; you can add it, quickly and easily, as part of an upgrade, retro-fit or repair. Firesleeve Hook & Loop simply clips on to the pipe or cable, without the need to disconnect the system to slide it along the length.

Fire sleeve is available in six standard colours – true red oxide, blue, silver, black, yellow and bright red – to help distinguish hot and cold pipework, live electrics, earth connections and more. And if you need additional colours, just ask.
