Heat-Resistant Silicone Tube
−60°C to +220°C
Main applications
silicone tubing that protects hot wiring and pipework completely
Key Features
Wide service range: −60°C to +220°C
Heat and cold resistant together — covering cryogenic cooling lines through to hot steam and heating circuits in one material
Electrically insulating protection
The excellent dielectric properties of silicone — a high-temperature protective sleeve for wiring, preventing shock and leakage
Excellent flexibility and recovery
Highly elastic silicone flexes without cracking at pipe bends and on moving cable runs
Chemical, ozone and UV resistance
The chemical resistance inherent in silicone — stable long term against ozone, UV, acids and alkalis
Food, pharmaceutical and electrical safety grades
FDA-grade silicone available — applicable to internal food machinery piping and pharmaceutical process lines
