Typical Applications
Steel Mills and Foundries
Helps protect hoses, cables and pipes from radiant heat and molten-metal splash near casting and metal-processing areas.
Hydraulic Equipment Near Furnaces
Reduces direct thermal exposure that can harden, crack or prematurely age hydraulic hose covers.
Welding and Hot-Work Cells
Shields service lines from intermittent sparks, heat and nearby flame sources where routing cannot be moved farther away.
Engine and Exhaust Zones
Provides an insulating layer around compatible lines routed near hot manifolds, exhaust components or industrial engines.
Measure the largest outside diameter along the protected assembly, including joints, clamps and local enlargements. Choose an ID that permits installation without compressing the hose or leaving an unnecessarily loose sleeve.
Map the heat source, distance, orientation, exposure time and whether the hazard is radiant heat, direct flame or molten splash. Check bends and movement through the full equipment cycle. Define how the sleeve ends will be secured and protected from fraying or contaminant entry.

Frequently Asked Questions
01. What is a silicone-coated fiberglass fire sleeve used for?
A silicone-coated fiberglass fire sleeve protects hydraulic hoses, cables and pipes operating near high-temperature sources. It helps reduce the effects of radiant heat, flame and molten-metal splash.
02. What is the continuous operating temperature of GF-FH-SR?
The specified continuous operating temperature range is −50°C to +260°C. Peak thermal exposure is different from continuous service temperature and must not be interpreted as a continuous operating rating.
03. How do I select the correct fire sleeve diameter?
Measure the maximum outside diameter of the hose, cable, pipe or complete bundle, including fittings and enlarged sections. Allow for bends and installation clearance, and select an ID that permits installation without excessive looseness or restricted movement.
04. How should GF-FH-SR be inspected and maintained?
Inspect the sleeve periodically according to the equipment maintenance plan for coating cracks, damage, wear, contamination or loose ends. If significant damage is found, reassess its suitability for the operating thermal conditions and replace it when necessary.
