Silicone hoses are a type of flexible tubing made from high-quality silicone material.
Silicone hoses are known for their excellent heat resistance, making them ideal for use in high-temperature environments. They can withstand temperatures ranging from -50°C to 200°C (-58°F to 392°F) without losing their physical properties.
These hoses are also highly flexible, allowing for easy installation and maneuverability in tight spaces. They have a smooth inner surface that minimizes flow resistance and prevents the build-up of contaminants or bacteria.
One of the main advantages of silicone hoses is their durability and resistance to aging. They are resistant to ozone, UV radiation, moisture, and chemicals, ensuring a long lifespan and minimal maintenance requirements.
Silicone hoses are available in various sizes, shapes, and colors to suit different applications. They can be reinforced with polyester or fiberglass to enhance their strength and pressure resistance.
Automotive applications: Silicone hoses are widely used in automotive cooling systems, turbocharger systems, and intake systems. They provide reliable performance and withstand the high temperatures and pressures generated by engines.
