High Temperature Fiberglass Sleeving is a premium insulation and protective solution designed for applications exposed to extreme heat, fire risk, and harsh industrial conditions. Made from woven fiberglass yarn and enhanced with protective coatings, this heat resistant fiberglass sleeve provides reliable protection for cables, wires, and electrical components in automotive, aerospace, electrical, and industrial systems.
As a trusted solution for high-performance insulation, fiberglass high temperature sleeving ensures long-term safety, durability, and stable performance even under continuous thermal stress.
High temp Fiberglass Sleeving is a flexible tubular insulation material made from braided or woven fiberglass fibers. It is designed to withstand high thermal loads while maintaining structural integrity and electrical insulation performance.
Also known as Fiberglass Sleeving, Fiberglass Tube, or high temperature fiberglass sleeving, this material is widely used where conventional insulation materials fail under heat exposure.
Fiberglass Sleeve Temperature Resistance
One of the most important features is its excellent thermal stability:
Continuous operating temperature: up to 260°C (500°F)
Short-term exposure: up to 537°C (1000°F)
Stable performance under thermal cycling conditions
The fiberglass sleeve temperature rating makes it suitable for demanding high-heat environments such as engines, industrial machinery, and electrical systems.
