Sleeve

Product Overview

Darco Southern offers a variety of high temperature sleeve products; each providing unique physical characteristics and sealing performance.  Common applications for high temperature sleeves include protecting hoses, wires, and cables against weld splatter, fire, extreme heat, and molten metal. Even at elevated temperatures the most of our sleeves are resistant to most acids and alkalis.

Braided Fiberglass Sleeve

Tetraglas® Sleeve is braided with high-quality Type E fiberglass yarns. Fiberglass sleeve will not burn and is suitable for use in applications with temperatures up to 1000°F (540°C). Braided fiberglass sleeves provide flexibility, durability, and thermal containment. This sleeving can be heat treated or coated with vermiculite, PTFE, graphite, or acrylic saturant.

Knitted Fiberglass Sleeve

Knitted fiberglass sleeve provides exceptional thermal protection and containment. With excellent flexibility, applications with bends or other obstructions are a good fit for this sleeving. The knitted construction allows neat, easy field-cutting. Knitted fiberglass sleeve can typically be provided in longer bulk lengths than braided due to the manufacturing process, thereby minimizing material handling & wastage and maximizing process productivity.

Expandable Braided Fiberglass Sleeve

Expandable braided fiberglass sleeve is specially constructed to provide maximum flexibility and expansion (up to 2x relaxed diameter) to accommodate installation over fittings, couplings and other in-line obstructions that inhibit standard sleeves.  Expandable braided fiberglass sleeve can be provided with a saturant coating to minimize fray and increase abrasion resistance.

Basalt Sleeve

Knitted Basalt Sleeve is constructed with basalt fiber yarns knitted into a durable, heavy-wall sleeve to provide an exceptional combination of enhanced heat resistance, thermal performance, and durability when compared to typical fiberglass sleeve products. This knitted construction has excellent flexibility making it optimal for installation around tight bends and over fittings, couplings, and other obstructions. The dense single-wall design provides optimal coverage and minimizes snagging during installation. Rated for 1400°F (750°C), basalt sleeve provides an excellent thermal insulation for exhaust systems and radiant heat protection for the surrounding components.

Silica Sleeve

Tetraglas 3000® sleeve is braided using amorphous silica yarns. Silica sleeve will not burn and is suitable for use in continuous temperatures to 1800°F (980°C). This product is only available with a 1/16” wall thickness. Vermiculite coating can be applied for increased abrasion resistance.

Firesleeve

Silco Sleeve® firesleeve is designed to protect hoses, wires and cables from the hazards of intense heat and occasional direct flame. It protects continuously to 500°F (260°C) and will withstand a molten splash at 2200°F (1200°C). Made of either knitted or braided fiberglass yarns in a flexible substrate, it is then coated with a high-grade, fully-cured silicone rubber. Resistant to hydraulic fluids, lubricating oils, and fuels, firesleeve insulates against energy loss in piping and hosing, protects employees from burns and provides flame resistant “bundling” of wires, hoses, and cables . Both Aerospace and Industrial firesleeve are coated with the same proprietary silicone rubber compound for increased durability and enhanced heat & flame protection.
 

In addition to these standard lines, our sewing department has the capability to create sleeves from any of our standard woven cloths that are too large for braided or knitted sleeves or to create a flexible cover with the addition of Hook and Loop or other closures.
