Testimonials
With a temperature resistance range of -65°C to 260°C, RONTEIX 1-inch silicone hose is suitable for high-temperature environments such as turbocharger systems, intercooler systems, and engine cooling systems.
When using a 1-inch silicone hose to transport low-pressure air or water, minor deviations are acceptable. If high pressure or leak-prone fluids are involved, it is best to ensure that the fitting size matches the hose’s inner diameter. If necessary, consider using a silicone reducer hose to connect the fitting to the pipe.
1 inch silicone hose is prone to swelling, softening, or a decline in performance when exposed to oil or fuel, so it is not suitable for transporting fuel or gasoline. You may want to consider an FKM-lined hose for transporting gasoline, as it is resistant to oil and chemicals.
With good flexibility and high-temperature resistance, 1 inch silicone hose is perfect for automotive engine intake systems, engine cooling systems, automotive heating systems, CAC systems, and industrial equipment.
Yes. If you provide samples, part numbers, or 3D drawings, RONTEIX can customize the color, size, wall thickness, reinforcement, and logo of your 1-inch silicone hose.
The service life of 1 inch silicone hose is approximately 3 to 10 years, which is affected by temperature, pressure, reinforcement, and the conveyed medium.
RONTEIX supplies and manufactures 1″ (25 mm) silicone hoses in a variety of colors, bend angles, reinforcements, lengths, and wall thicknesses. We offer OEM and ODM services and can customize automotive coolant hoses, radiator hoses, heater hoses, and CAC hoses for you.
