High-Temperature Knitted Fiberglass Sleeve
Basic Info
Up to 550–760°C*
Flexible Knitted Construction
Excellent Thermal Insulation
E‑Glass Fiber
Asbestos‑Free
Problem Description
Your Component Doesn't Need to Touch the Heat
A pipe can survive the heat.
A hose can survive the pressure.
A cable can carry the current.
But when these components are routed too close to a furnace, exhaust, hot pipe or molten‑metal process, the surrounding heat can become the real problem.
The result can be:
Premature hose aging
Cable insulation degradation
Excessive surface temperature
Heat transfer to nearby components
Personnel burn hazards
Unwanted heat loss
Reduced service life
Personnel & Equipment Protection
It Doesn't Just Protect the Component.
It Can Protect the People Around It.
Imagine a technician working beside a machine.
The hydraulic hose is carrying hot fluid.
The pipe is operating at high temperature.
The exhaust is radiating heat.
The equipment is working perfectly.
But the exposed surface is too hot to touch.
A flexible fiberglass sleeve can create an insulating layer around the hot assembly, helping reduce direct contact with the hot surface and improve working‑area safety.
Commercial glass‑fibre and firesleeve products are specifically used for personnel protection against hot hoses, steam lines and hot pipework.
Protect the equipment.
Protect the surrounding components.
Protect the people working beside it.

Temperature‑Based Material Selection
FROM 550°C TO 1200°C+: WE CAN HELP YOU CHOOSE
Your temperature determines your material.
550–650°C → Knitted / Braided Fiberglass
~760°C → Higher‑temperature fiberglass / Basalt
~1000°C → Silica / Ceramic
1200°C+ → Quartz / specialized high‑temperature materials
These are application‑dependent ranges, not universal operating guarantees; the actual selection must consider exposure time, heat‑transfer mode, mechanical conditions and any flame/molten‑metal exposure. Commercial suppliers offer fiberglass, basalt, silica, ceramic and quartz constructions across progressively higher temperature ranges.
