Coated Tube / Heat-Resistant Tube
Up to 250°C
Main applications
coated and heat-resistant tubing delivering insulation and heat resistance together
Key Features
Insulation rated 200–250°C continuous
Glass fiber with a silicone coating — the highest heat-resistant insulating solution for hot cable sheathing
Insulation and heat resistance in one
The dielectric properties of the silicone coating with the heat resistance of glass fiber — the standard for wiring protection in hot electrical plant
Abrasion and wear protection
The coated tube construction protects the wiring inside from friction and impact
Flexible, easy around bends
The flexibility of the silicone coating suits wiring protection around bends and in vibration
Every bore size
∅2 mm to over ∅100 mm — matched to cable gauge and diameter
