HTG Sleeves (High-Temperature Glass fiber Sleeves) are premium-grade thermal insulation sleeves engineered for the most demanding high-heat environments. Manufactured from densely braided, heavily treated glass fiber yarns, these sleeves are designed to withstand continuous temperatures of up to 650°C and short-term exposure to even higher peaks. The high-density construction ensures superior thermal insulation, mechanical integrity, and resistance to abrasion, making them an ideal choice where thermal containment and flame resistance are non-negotiable. Their construction allows them to shield cables, hoses, and pipes from direct flame, molten metal splash, and extreme radiant heat.

These sleeves are extensively used in extreme industrial environments such as furnaces, steel mills, refineries, foundries, and metal processing plants, where conventional sleeves would degrade rapidly. Their ability to endure intense heat and physical stress makes them essential for protecting wiring and hydraulic systems exposed to molten slag, welding sparks, or radiant heat sources. Industries such as metallurgy, petrochemical, glass manufacturing, and thermal processing rely on HTG Sleeves to maintain operational safety, prolong equipment life, and ensure uninterrupted high-temperature performance.
