Frequently Asked Questions
Our silicone tubing complies with ISO 13485 standards for the biological evaluation of medical devices. It undergoes rigorous testing to confirm it does not cause cytotoxicity, sensitization, or skin irritation, making it suitable for medical and food-grade applications.
The silicone tubing operates stably across a wide temperature range of -60℃ to 220℃. It maintains its physical properties and flexibility at both extreme low and high temperatures, making it ideal for demanding industrial and automotive environments.
Yes. We offer a wide range of inner diameters from Φ0.4mm up to Φ75mm and various wall thickness options. All specifications can be fully customized according to customer drawings and requirements. Please contact us with your exact dimensions for a tailored quote.
The tubing supports multiple sterilization methods including autoclaving (steam sterilization), gamma irradiation, and ethylene oxide sterilization. For routine cleaning, water, alcohol, or medical-grade detergents are all suitable. Avoid prolonged contact with strong acids, alkalis, or solvents without prior compatibility testing.
This silicone tubing is widely used across multiple industries including automotive (fuel and brake lines), industrial machinery (hydraulic systems), aerospace & defense (aircraft fuel systems), renewable energy (solar thermal systems), pharmaceutical manufacturing, food processing, and heavy equipment & mining applications.
The tubing is available in four Shore A hardness grades: 40A, 50A, 60A, and 70A. Softer grades (40A–50A) offer greater flexibility and higher elongation (up to ≧500%), while harder grades (60A–70A) provide higher tear strength (up to ≧40 kN/m) and are better suited for high-pressure or abrasion-resistant applications.
