Electrical Insulation Sleeving

Silicone-Coated Fibreglass Sleeving
Flexible High-Temperature Insulation for Wires & Cables

Silicone-coated fibreglass sleeving provides reliable thermal and electrical insulation for wires, leads, terminals and cable assemblies operating in elevated temperature environments. Constructed from a woven fibreglass sleeve with a flexible silicone rubber coating, it offers excellent dielectric strength, abrasion resistance and long-term durability.

Commonly used in electric motors, transformers, switchgear, heating equipment and industrial control systems, this sleeving helps protect conductors from heat, mechanical wear and environmental exposure.
