Frequently Asked Questions
-
Q What temperature range can your silicone rubber tubes withstand?Our silicone rubber tubes operate stably from -60℃ to 250℃ under continuous use, and can endure short-term peak temperatures up to 300℃. This wide range makes them suitable for both high-heat industrial processes and demanding cryogenic applications.
-
Q Are your silicone tubes resistant to chemicals, oils, and solvents?Yes. Our silicone rubber tubes exhibit superior resistance to acids, alkalis, solvents, fuels, and lubricants. They maintain structural integrity and performance even when continuously exposed to corrosive substances in industrial environments.
-
Q What inner diameter sizes are available, and can they be customized?Standard inner diameters range from 3mm to 50mm and above. We support full customization of inner diameter, wall thickness, color, and reinforcement type to meet your specific application requirements. Please contact us with your specifications for a tailored quote.
-
Q What industries are your silicone rubber tubes most commonly used in?Our tubes are widely used across the automotive industry (fuel lines, turbocharger hoses), industrial machinery (hydraulic and pneumatic systems), aerospace and defense (aircraft fuel systems), renewable energy (solar thermal, wind turbines), and heavy equipment and mining applications.
-
Q How should silicone rubber tubes be stored and maintained?Store tubes in a cool, dry environment away from direct sunlight and ozone-generating sources such as electric motors. For cleaning, industrial solvents or steam cleaning are suitable. Food-grade variants should follow specific sterilization protocols. Always test fluid, pressure, and temperature compatibility before full deployment.
-
Q What is the standard pressure rating of your silicone rubber tubes?Standard silicone tubes are rated up to 10 bar (145 psi). Reinforced versions—featuring high-tensile polyester fabric or stainless steel wire braid—can handle significantly higher pressures. Please provide your working pressure requirements so we can recommend the most suitable product.
