Firesleeve: Heavy Duty - High Temperature, Heat, Flame &
Pyro Resistant Jacket Silicone Rubber Coated Fiberglass Sleeve
Weld Splatter, Slag and Spark - Molten Metal Splash Protection
500°F / 260°C Continuous Exposure:
FlameShieldTM heavy duty high temperature, heat, flame and pyro resistant firesleeve jacket is manufactured to endure the harshest of environments of heat, flame, fire, molten metal.
It is used to protect wires, cables, hydraulic hoses, pipes and lines from welding splatter and slag, molten metal splash, grinding and welding sparks, fire and flame exposure.
Firesleeve is available in sizes ranging from 0.25" Inside Diameter through 5" I.D. in 25 size steps.
Heavy Duty Internal Braided Firesleeve
Molten metals simply slide off of the extra heavy duty coating of High-Temperature Silicone Rubber on all of these products (firesleeve), providing excellent burn-through protection.
Firesleeve pyro resistant sleeve & jacket withstands molten splash & welding splatter. Withstands 500°F / 260°C continuous exposure; 2200°F / 1205°C for periods up to 15 minutes and short flash excursions to 3000°F / 1650°C.
Firesleeve is highly flexible and conformable.
Firesleeve ends can be dipped in our SleeveSeal liquid silicone rubber end seal to prevent wicking of liquids and contamination.
SleeveSeal tape can be used to seal the ends of sleeve at the connector for a watertight seal. Also protects the clamp if used.
