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.
500°F / 260°C Continuous Exposure: Higher Intermittent
High Temperature, Heat, Flame, Fire & Pyro Resistant Silicone Rubber Coated
Fiberglass Sleeve with Velcro: Firesleeve with Velcro Closure
Firesleeve with Velcro®
Firesleeve with Velcro (Firesleeve VC) is the perfect choice for protecting hydraulic hoses and lines, pneumatic lines, fuel & oil lines, brake lines, wires and cables from exposure to high temperature, heat, flame, fire, & pyro conditions. The extra thick special formulation of silicone rubber sheds molten metals, slag, welding splatter, electrical or grinding sparks and contamination. Silco Shield VC also provides protection from ozone, UV and abrasion.
The standard colour is red-oxide.
We take our heavy duty braided substrate firesleeve and add Velcro® hook and loop to result in a firesleeve than can be easily installed on long hose or cable runs, or on hose and cables that cannot be detached from their installation. This retrofit solution allows the sleeve to be added, or replaced conveniently - this makes for an easy to use Electic Arc Furnace cable cover (EAF cable cover).
The smallest standard I.D. is 1/2" and the largest standard I.D. is 12". Larger I.D.s are possible by fabricating multiple fabric widths together, with an almost limitless I.D. size being the result. Firesleeve with Velcro uses 3/4" wide Velcro® on IDs from 1" through 3 3/4" and 2" wide Velcro® on 4" through 12" I.D. fabrications.
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.
Materials that resist catching fire, burn slowly, or retard burning can be described as either "incombustible", "non-flammable", "non-combustible", "fire-resistant" or "fire-retardant". "Self-extinguishing" materials cease burning once the flame or heat source is removed. "Fireproof" is understood to mean that an object cannot burn, but few materials are truly fireproof.
Most of our products fall within one or more of the above descriptions: they resist high temperature, flame, fire, molten metal splash and weld splatter very well but may melt with prolonged exposures past their designed maximum continuous operating temperature. They can also provide OSHA, ANSI-FM & NFPA compliance and personnel protection.
Using our products to retain heat or cold within pipes, hoses, enclosures or equipment helps conserve energy and resources, and reduces operating costs.

This photo shows the standard edge of the sleeve: some loose fibers of the fiberglass base material are always present at the very edge. This does not affect the performace of the sleeve and is an aesthetic concern only.
This photo shows the standard edge of the sleeve with a serged overlock added. The overlock holds the loose ends of the base material fibers. The velcro closure is then added over the serging. This overlocked edge is available at extra charge.
This photo shows the sleeve in place wrapped around a cable.
The overlapping edge of the right-hand section of the sleeve is sealed with a spiral wrap of end wrap tape, completely sealing the sleeve from exposure to contamination.
The end wrap tape can be easily removed if necessary, allowing the velcro sleeve to be opened or removed from its installation.
