Frequently Asked Questions (FAQ)
-
What temperature range can silicone rubber hoses withstand? +Our silicone rubber hoses operate stably from -60℃ to 250℃, with short-term tolerance up to 300℃. This makes them suitable for both high-heat industrial applications and cryogenic environments, far exceeding the range of standard rubber hoses.
-
What is the standard pressure rating for these silicone hoses? +Standard silicone tubes are rated up to 10 bar (145 psi). Reinforced versions with polyester fabric or stainless steel wire braid can achieve significantly higher pressure ratings. Please contact us with your specific pressure requirements for a customized solution.
-
Can the inner diameter and color be customized? +Yes. Inner diameters range from 3mm to 50mm and can be customized beyond this range upon request. Standard colors include black and gray; custom colors such as red for high-temperature identification are also available. Please provide your specifications when inquiring.
-
Are these hoses suitable for food and pharmaceutical applications? +Yes. Our food-grade silicone hoses are made from high-purity platinum-cured silicone rubber that meets relevant food safety standards. They are widely used in beverage filling lines, pharmaceutical machinery, and other sanitary applications. Food-grade variants support steam cleaning and specific sterilization protocols.
-
How should silicone rubber hoses be stored and maintained? +Store hoses in a cool, dry place away from direct sunlight and ozone sources such as electric motors. During installation, use appropriate industrial clamps or fittings and avoid over-tightening or misalignment. Regular inspection for signs of wear, cracking, or leakage is recommended to ensure long service life.
-
What industries are silicone rubber hoses most commonly used in? +Silicone rubber hoses are widely used across the automotive industry (fuel lines, turbocharger hoses, coolant systems), industrial machinery (hydraulic and pneumatic systems, chemical transfer), aerospace and defense, renewable energy (solar thermal, wind turbines), and heavy equipment and mining sectors.
