Key Features
🔥
1000°C protective sleeving
Braided silica fiber sleeve — protecting wiring, cable and hose completely in extreme heat
🛡️
Abrasion and wear protection
The braided tube construction protects the cable or hose inside from friction and impact
⚡
Dielectric properties
Inorganic silica — retaining electrical insulation at temperature
📏
A wide range of bore sizes
Inside diameters from 5 mm to over 100 mm — matched to cable gauge and hose size
🔄
Flexible sleeve or rigid tube
Braided sleeve (flexible) or rigidised silica tube — the right form for the application
