Velcro Firesleeve is a heavy-duty, high-temperature protective sleeve designed to protect hoses, cables, and industrial pipelines from heat, flame, and mechanical damage. Unlike traditional fire sleeves that require installation from one end, this Velcro Firesleeve features a hook-and-loop (Velcro) closure, allowing fast installation and removal without disconnecting equipment.
As a reliable solution for thermal protection systems, it is widely used in aerospace, automotive, hydraulic systems, marine engineering, and industrial machinery.
What Is Velcro Firesleeve?
A Velcro Firesleeve is a fire-resistant insulation sleeve made from fiberglass braided fabric coated with silicone rubber, combined with a Velcro (hook-and-loop) fastening system.
Compared with standard fire sleeves, this design allows the sleeve to be wrapped around existing hoses or cables directly, making it ideal for maintenance, retrofit projects, and emergency repairs.
It is commonly used to protect:
