Zetex® Fiberglass Sleeves are flexible, braided, thermal insulation sleeves used to protect hydraulic and electrical lines, cable, or wiring from high temperatures. Fiberglass sleeves are also commonly known as “fiberglass tubing” or “fiberglass sleeving”.
Zetex® Fiberglass heat resistant sleeves are woven from the same premium highly texturized DE glass yarn used to make Zetex® Fiberglass Fabrics. An over-spray process preserves that texturization during fabrication and in use. The over-spray coating is made from inorganic materials so it will not produce hazardous out-gassing.
How Much Heat Can High-Temperature Insulation Sleeves Withstand?
Zetex® fiberglass sleeves support temperatures up to 1000°F / 540°C. Any Zetex® fiberglass sleeve can be treated with the ZetexPlus® Vermiculite Coating to double temperature resistance to 2000°F / 1095°C and improve abrasion resistance.
The Zetex heat resistant sleeves are also available with custom diameters and can be treated with custom high temperature coatings. Minimum order requirements apply. Contact us for more information.

FAQs About Heat-Resistant Sleeves
Q1. Where are insulating fiberglass sleeves used for?
Insulating fiberglass sleeves are used on cables, wiring, hydraulic lines, and hoses to protect them from high heat, abrasion, and harsh industrial or environmental conditions.
Q2. Are texturized fiberglass fabrics good for high-temperature insulation?
Yes. The trapped air in texturized fiberglass lowers thermal conductivity, making it more effective at resisting heat transfer than standard fiberglass yarns.
Q3. Do fiberglass sleeves offer abrasion resistance?
Standard fiberglass sleeves offer good thermal protection, and when treated with ZetexPlus Vermiculite Coating, their abrasion resistance and flame performance are further enhanced.
