Flexible Varnish Tube with Silicone Coating 16 mm, Class C, 3 kV

Product Name:
Braided glass fibre sleeving with exterior silicone rubber coating – 3 kV, Class C

Description:
This flexible, braided glass fibre sleeving is coated on the outside with high-temperature resistant silicone rubber. Its woven structure allows for a minimum expansion ratio of 1:1.5, meaning the tube can significantly expand beyond its nominal diameter. This makes it easy to apply over wires, cables, and components of various shapes and sizes. This property is especially advantageous during installation, particularly in tight or hard-to-access areas.

The product offers excellent thermal resistance, electrical insulation, and mechanical protection, making it ideal for industrial, electronic, and railway applications.
