Red Silicone And Glass Fiber Flex Hose What Is?
What is a Red Silicone and Fiberglass Flex Hose?
The red silicone and fiberglass flex hose is a flexible hose made from silicone material coated over a fiberglass braid, typically used in applications requiring high temperature resistance and flexibility. These hoses are especially preferred in heat-resistant air, smoke, and steam transfer systems.
Technical Description
- Inner structure: High temperature resistant fiberglass braid
- Outer coating: Flame retardant and heat-resistant red silicone
- Form: Flexible, lightweight, and bendable structure
- Operating temperature: Typically between -60°C and +250°C (can withstand up to 300°C momentarily)
Applications

Advantages
| Feature |
Description |
| High temperature resistance |
Withstands continuous 250°C and short-term 300°C |
| Heat insulation |
Fiberglass structure reduces heat transfer to the outer surface |
| Flame retardant |
Does not propagate flames, contributing to fire safety |
| Flexible and lightweight |
Easy installation and use in tight spaces |
| Moisture, chemical and UV resistance |
Durable thanks to silicone coating |
Important Considerations
- Not highly resistant to mechanical abrasion (external protection may be needed).
- If used under pressure, manufacturer’s pressure limits must be checked.
- Must be secured with appropriate clamps or flanges.
