A silicone fire sleeve is a flexible insulating casing. It features a core of thick fiberglass yarn, which is enveloped by a thickened flame – retardant silicone layer on the outside. Through comprehensive testing, it has been determined that its flame – retardant grade reaches an impressive VW1 level.
Where Are Silicone Fire Sleeves Commonly Applied?
Residential Use: In households, gas pipes and water heater pipes often require external anti – scalding and fire – prevention protection, where silicone fire sleeves can play a crucial role.
Automotive Industry: Inside vehicles, all wiring harnesses, hoses, and exhaust pipes need heat insulation and flame – retardant safeguarding. Silicone fire sleeves are ideal for providing this protection.

Mechanical Equipment
Many mechanical devices and associated pipelines demand high temperature and fire protection, making these sleeves a suitable solution.
Marine Applications
For ships, the wiring harnesses on the exterior need to be insulated and shielded, and silicone fire sleeves can fulfill this requirement effectively.
However, the most prevalent application of silicone fire sleeves is to offer flame – retardant protection for the exteriors of metal braided pipes and hydraulic hoses.
