Our products meet the rigorous demands of automotive applications, contributing to vehicle safety and efficiency by maintaining integrity and reliability in critical areas.

  • Versatility: Automotive seals come in many size specifications, acting as gaskets, weatherstrips, and trims, sealing various components and keeping vehicles running smoothly.
  • Durability: Built to endure the toughest conditions, automotive rubber can handle extreme temperatures, sunlight, and road chemicals, ensuring long-lasting performance.
  • Precise Fit: Manufactured with unmatched precision, automotive seals meet exact specifications for a perfect fit, crucial for effective vehicle assembly and efficiency.
  • Flexibility: Automotive rubber is designed to bend and conform, fitting into complex shapes and tight spaces within vehicles.
  • Long-Lasting: Resistant to wear, tear, and pressure, automotive rubber extrusions provide reliable performance and contribute to the overall lifespan of your vehicle.
  • Quiet Running: Effective sealing keeps out water, dust, and noise, creating a comfortable and quiet driving experience.
  • Resistance to Chemicals: Our automotive rubber extrusions are also resistant to a wide range of chemicals, ensuring that they maintain their integrity and performance even when exposed to harsh substances.

Some key applications and uses of silicone in the automotive industry are:

  • Seals and Gaskets: Silicone is a popular choice for seals and rubber gaskets throughout a car because of its excellent resistance to heat, oil, and chemicals. These seals prevent leaks of fluids like oil, coolant, and transmission fluid, and also keep out dust, dirt, and moisture.
  • Hoses and Belts: Silicone hoses are used in various parts of a car's engine compartment, cooling system, and intake system. They are preferred over traditional rubber hoses because of their superior flexibility, durability, and resistance to high temperatures.
  • Spark Plug Boots: Silicone is used to make the boots that insulate the spark plugs in a car's engine. These boots need to withstand high voltage and extreme temperatures, and silicone is an ideal material for this application.
  • Wire and Cable Insulation: Silicone, however, excels in withstanding high temperatures, typically functioning well from -40°C to +250°C. This ensures the wires maintain their integrity and don't short-circuit under the hood.
  • Wiper Blades: Many modern wiper blades are made from silicone. Silicone wiper blades conform better to the curvature of the windshield compared to traditional rubber blades, providing a clearer and more streak-free wipe.

Automotive Rubber Extrusions FAQs

What are the seals used in the automotive industry?

Our custom-made automotive rubber extrusions are expertly designed for the automotive industry. We use top-grade, automotive-specific silicone to create seals, gaskets, hoses, and trims that meet your specifications.

Engineered for durability and performance, our automotive rubber components can handle tough environments. They resist extreme temperatures, UV rays, and chemicals commonly found on the road.

What is the difference between a gasket and a mechanical seal?

Gaskets are used for sealing static connections within the engine, while mechanical seals are employed around moving parts to prevent fluid leakage in automotive applications.

What seals and gaskets are on an engine?

Some key seals and gaskets in an engine are:

  • A cylinder head gasket - The most critical gasket in an engine. It seals the combustion chamber and prevents engine oil, coolant, and combustion gases from mixing.
  • Valve cover gasket - Located on top of the cylinder head, the valve cover gasket seals the valve train area, preventing engine oil from leaking out.
  • Water pump gasket - This gasket forms a seal between the water pump housing and the engine block. It ensures coolant doesn't leak from the water pump, which is vital for maintaining engine temperature.
  • Timing cover gasket - The timing cover gasket seals the timing cover, which protects the timing belt or chain and other components involved in valve timing. A leak here could allow oil leaks or contamination of the timing belt.
  • Thermostat gasket - This small gasket sits between the thermostat housing and the engine block. It ensures coolant flow is directed properly by the thermostat based on engine temperature.
  • Camshaft and crankshaft seals - These are circular seals placed around the camshaft and crankshaft where they exit the engine block. They prevent engine oil leaks from these rotating shafts.
