Aging-Resistant Industrial-Grade Silicone Braided Tube - Top China Suppliers & Factory Quality
Core Features & Advantages
-
◎ Exceptional Pressure Resistance & Structural Stability
The multi-layer braided reinforcement acts as a robust pressure-bearing skeleton, enabling working pressures of 10–50 Bar and burst pressures up to 3–6 times the rated value. This structure effectively prevents collapse during vacuum suction or under high negative pressure, ensuring stable transmission in high-pressure differential environments.
-
◎ Superior Temperature & Weather Resistance
Inheriting the wide temperature range of silicone, its continuous operating temperature spans from -60℃ to 200℃ (some models from -73.3℃ to 204.4℃), with short-term tolerance for even higher temperatures. It maintains elasticity and stable performance in extreme climates and resists ozone and UV aging.
-
◎ Excellent Chemical & Mechanical Resistance
The silicone inner liner offers good tolerance to a wide range of acids, alkalis, oils, solvents, and industrial chemicals. The braided reinforcement provides high tensile strength, abrasion resistance, and kink resistance. The optimized braiding angle and density enhance the hose's durability in complex bending layouts, preventing flattening or rupture.
-
◎ Smooth Bore & Fluid Compatibility
The smooth inner wall minimizes fluid resistance, reduces media retention, and facilitates cleaning, effectively lowering cross-contamination risks and meeting high-standard industrial requirements. The semi-transparent wall allows for visual monitoring of fluid flow.
-
◎ Long Service Life & High Reliability
Designed for extended service life, it maintains stable performance in harsh industrial environments, significantly reducing system maintenance costs and downtime.

Usage Instructions
-
1
◎ Installation & Connection
Use industrial-grade clamps or quick-connect fittings matched to the hose diameter to ensure a reliable seal. Avoid excessive bending, stretching, or twisting during installation. Refer to the specific product specifications for the minimum bend radius.
-
2
◎ Cleaning & Sterilization
Can be cleaned using suitable industrial cleaners, hot water, or steam based on the media properties. Some models support CIP (Clean-in-Place) and SIP (Sterilize-in-Place). Non-food-grade products should not be used in food-related cleaning processes.
