Frequently Asked Questions (FAQ)
1
What temperature range can the silicone rubber hose withstand?
The silicone rubber hose operates stably from -60℃ to 250℃, with short-term tolerance up to 300℃. This makes it suitable for both high-heat industrial processes and cryogenic applications without compromising performance or structural integrity.
2
What inner diameter sizes are available, and can they be customized?
The standard inner diameter range is from 3mm to 50mm+. Custom sizes are available upon request to meet specific application requirements. Please refer to the specification sheet for detailed tolerance data across various diameter ranges.
3
Is the silicone hose suitable for food-grade or pharmaceutical applications?
Yes. The hose is made from high-purity platinum-cured silicone rubber, which meets stringent hygiene and safety standards. Food-grade variants are available and can be used in beverage filling lines, pharmaceutical machinery, and other clean-process environments. Specific cleaning protocols should be followed for these applications.
4
What is the maximum pressure rating for these silicone hoses?
Standard silicone tubes are rated up to 10 bar (145 psi). Reinforced versions — incorporating polyester fabric or stainless steel wire braid — support significantly higher pressure ratings. Please contact us with your specific pressure requirements for a customized solution.
5
How should the silicone hose be stored and maintained to extend its service life?
Store the hose in a cool, dry location away from direct sunlight, UV radiation, and ozone sources such as electric motors. Clean with appropriate industrial solvents or steam as needed. Regularly inspect for abrasion, kinking, or fitting looseness to ensure safe and optimal performance.
6
What colors and reinforcement options are available for the silicone hose?
Standard colors include black and gray. Custom colors are available — for example, red is commonly used for high-temperature applications for easy visual identification. Reinforcement options include high-tensile polyester fabric braid and stainless steel wire braid, depending on the required pressure and mechanical strength specifications.
