High Temp Sleeving

Fibreglass Sleeving – 220°C Rated
Thermal Protection for Electrical Leads & Terminals

Engineered for thermal and electrical protection, our natural fibreglass sleeving is designed for use in high-temperature environments where durability and insulation are critical. Commonly used to insulate wires leading to terminals, start switches, and other electrical connection points, this sleeving helps prevent shorts, abrasion, and heat damage.

Key Features:

• High Temperature Rating: Continuous use up to 220°C; short-term resistance up to 260°C
• Size Range: Available in diameters from 1.0 mm to 50 mm
• Rugged Protection: Shields wiring from moisture, abrasion, and harsh chemicals
• Flexible Fit: Easy to slide over conductors and route through tight spaces
• Reliable Insulation: Reinforced with glass fibres for long-term performance

Is fibreglass sleeving safe for long-term use in motors?

Yes – this 220°C rated natural fibreglass sleeving is designed for prolonged use in electric motors and high-voltage applications. It maintains strength and insulation integrity over time, even when exposed to elevated heat, oil, and vibration.

Commonly used in electrical repair shops, motor rewind workshops, marine and defence applications, and OEM equipment manufacturing, this sleeving delivers reliable insulation in environments where heat, vibration, and mechanical wear are factors.

Also known as fibreglass tubing insulation or heat-resistant cable sleeve, it is suitable for single and multi-core cables, exposed leads, or harnesses that demand high dielectric strength and mechanical protection.

This sleeving is ideal for motor rewinding, cable assemblies, wiring harnesses, and high-temperature insulation needs.
