Viessmann 7855644 Fiber Rope Seal 18X2100mm

Viessmann 7855644 Fiber Rope Seal 18 X 2100mm is a high-temperature sealing component used in heating systems, in boiler and combustion chamber assemblies. It is designed to form a tight gasket barrier around access doors, inspection covers, and flue connection points to prevent gas leakage and heat loss during operation in HVAC systems. This rope seal is commonly used in heating equipment where proper thermal resistance and stable sealing performance are required. Installed along mating surfaces, it supports better combustion operation by maintaining enclosure integrity within the heat exchange and exhaust sections of the system during routine heating cycles.
