The heavy-wall fiberglass braid and high-temperature resin treatment help reduce surface wear caused by friction, providing enhanced mechanical protection for cables and hoses in high-temperature environments.
•Reinforced Fiberglass Braid
Features a reinforced fiberglass braided construction to provide reliable thermal and electrical protection for cables and related components.
• High-Temperature Resin Treatment
High-temperature resin saturation enhances braid stability and improves abrasion resistance and handling performance.
•Thermal Protection Performance
Designed to protect cables, hoses and related components in high-temperature environments.
• Enhanced Abrasion Resistance
The reinforced fiberglass braid and resin treatment help reduce surface wear caused by friction, providing mechanical protection for cables and hoses in high-temperature environments.
• Stable Construction Under Mechanical Stress
The tight braided construction helps withstand vibration, mechanical stress and handling-related wear in demanding industrial environments.
• Multiple Sizes Available
Available in multiple standard inside diameters to accommodate different cable, hose and industrial component sizes according to installation space and protection requirements.

• Industrial motors and generators
Protects leads and cable exits exposed to heat, vibration and repeated mechanical movement.
• Metallurgy and furnace equipment
Adds reinforced insulation around control wiring and hoses near sustained high-temperature processes.
• Aerospace and automotive systems
Covers high-temperature harness sections where vibration, abrasion and compact routing occur together.
• Power conversion and electrical equipment
Insulates cables and bus-related connections that require a thicker protective wall and VW-1 performance.
• Industrial hose and sensor routes
Protects service lines passing through hot frames, clamps and equipment zones with significant contact wear.
How to Select
Measure both the normal route diameter and the largest component the sleeve must pass over. Check continuous temperature, peak events, voltage, vibration, abrasion and bend radius. A heavy wall improves mechanical protection but can affect flexibility and package size, so validate the completed assembly before production release.
• Sizes & Dimensions - Multiple standard inside diameters are available, with custom sizes subject to installation requirements for different cables and hoses.
• Braided Construction - Braid density, wall thickness and construction options can be reviewed according to project-specific protection requirements.
• Cut lengths - Different roll lengths and custom-cut pieces are available.
• Packaging - Customized spool configurations, product labeling and packaging options are available to meet bulk purchasing and delivery requirements.
GF-HT-O-EH Enhanced High Temperature Resistant Fiberglass Sleeving is designed to provide reliable thermal and electrical protection in demanding industrial environments.
