Fiberglass Sleeves

Our fiberglass sleeves are constructed from high-quality knitted, braided, or expandable braided E-glass fiberglass. These heavy-wall fiberglass sleeves provide thermal performance at 1000°F (540°C), making excellent thermal barriers as pipe, hose, and cable protection sleeves. Type E fiberglass will not burn and resists most acids, alkalis, bleaches, and solvents. Our saturated expandable fiberglass sleeve provides increased abrasion resistance and exceptional expansion capabilities for installation over fittings.

More Information

Knitted Fiberglass Sleeves

Knitted fiberglass sleeves provide a more economical thermal protection solution while still offering exceptional thermal containment. Knitted fiberglass sleeves can often be provided in longer bulk lengths than braided sleeves due to their unique manufacturing processes, thereby minimizing material handling and waste and maximizing productivity.

Braided Fiberglass Sleeves

Braided fiberglass sleeves provide durable thermal containment plus flexibility. Braided sleeves can be heat treated to burn off surface binders and minimize the off-gassing and smoke often encountered during the initial high-temperature exposure of untreated fiberglass. Braided fiberglass sleeves can also be coated with a saturant to minimize fraying and increase abrasion resistance or a vermiculite coating to provide the same saturant benefits with added performance at temperature extremes.

Expandable Braided Fiberglass Sleeves

Expandable braided fiberglass sleeves are specially constructed to provide maximum flexibility and expansion up to two times their relaxed diameter to accommodate installation over fittings, couplings, and other in-line obstructions that inhibit standard sleeves. Saturated expandable braided fiberglass sleeves can be manufactured with a vermiculite coating or a saturant coating to minimize fraying and increase abrasion resistance.
