Zdlinsulflex is a professional fire retardant sleeve manufacturer providing high-temperature protection solutions for hoses, cables, pipelines and industrial equipment. Made from high-quality fiberglass with silicone coating, our flame retardant sleeves offer excellent flame resistance, thermal insulation and protection against molten metal splashes.
Designed for demanding environments such as steel mills, foundries, rail transit and electrical systems, these fire protection sleeves help improve equipment safety and reliability. Customized sizes and OEM solutions are available to meet different industrial protection requirements.
Our flame retardant sleeves can withstand more than high ambient temperatures.
Its characteristics include:
Thermal insulation: The fiberglass structure reduces heat transfer from the surrounding environment to the protected component.
Flame resistance: The silicone-coated surface helps prevent flames from directly reaching the hose, cable, or pipe underneath.
Molten splash protection: The outer coating provides a protective surface against splashes from molten iron, aluminum, copper, and other heated materials.
Oil and moisture resistance: Silicone coating helps protect the sleeve in hydraulic, lubrication, and outdoor operating environments.
Flexibility and abrasion resistance: The fire protection sleeve can be installed around curved lines while providing additional protection against rubbing and mechanical wear.
Fire retardant sleeves create a flexible protective barrier between critical components and external heat sources. The fiberglass inner layer helps slow down heat transfer, while the silicone-coated outer surface provides additional protection against flames, sparks, molten-metal splash, moisture, oils, and common industrial contaminants.
When installed around hydraulic hoses, electrical cables, metal tubes, or corrugated pipes, the sleeve can help:
Reduce direct exposure to radiant and ambient heat
Protect component surfaces from sparks and hot particles
Minimize heat-related deterioration of cable insulation and hose covers
Extend the working life of equipment operating near furnaces or hot machinery
Improve personnel safety by covering extremely hot hoses and pipelines
Because the fire sleeve remains flexible, it can follow curved hoses and irregular routing without significantly increasing the overall size of the protected assembly.
