Automotive gasket manufacturers produce several types of rubber seals
Rubber washers
These flat rubber rings have an open center that allows fluid to pass through the connected parts. They provide a tight, non-abrasive seal in pipe and hose fittings to protects against leaks, vibration, and electrical charges.
Rubber gaskets
Gaskets are cut into various shapes and sizes from large sheets of rubber, which makes them highly customizable to meet the needs of specific fittings. They are widely used in the automotive industry to prevent leakage between connected parts due to their durability, color stability, temperature resistance, and general affordability.
Rubber bushings
Bushings absorb shock, minimize vibration, resist abrasion, and minimize or eliminate the need for lubrication between components. They are flexible and easy to use for parts like gear sticks, internal combustion, and suspension systems.
Silicone rubber tubing
Silicone tubing is a highly versatile product that resists frequent or continuous exposure to weather, UV radiation, heat, and ozone. This type of tubing sees extensive use in the automotive industry as an insulator for electrical cables and wires.
Applications of Rubber Seals in the Automotive Industry
Automotive rubber products play an important role in many applications in the automotive industry. Their primary uses in mechanical equipment include filling gaps between components, minimizing damage from vibration, preventing the leakage of liquids or gases, or hindering contamination from moisture or dirt.
Cooling system gaskets. These gaskets seal components within the system to prevent the coolant from leaking out.
Differential seals and gaskets. Highly flexible differential seals and gaskets are attached to the transmission axle to protect it from dirt, grime, and other contaminants that could damage the transmission.
Electrical junction boxes/fuse boxes. Electrical seals stop moisture and dirt from getting into the electrical system where they could cause sparks, fires, shorts, or other malfunctions.
Engine seals and gaskets. These seals and gaskets absorb excess heat and compression while ensuring that oil, fluids, or coolant don’t leak into or out of the engine compartment.
Fuel supply gaskets. Placed in between the fuel pump mounting surface and the fuel pump space, fuel supply gaskets maintain pressure within the engine compartment.
Transmission seals. Transmission seals and gaskets are used in internal and external transmission components to create pressure-tight connections in accumulators, servos, clutch packs, and transmission axle cases.
Windshields. The seals and gaskets used around windshields are an important factor in safety and comfort, maintaining air quality, cushioning the windshield against flexing movements, and protecting the occupants from wind, water, and noise.
Advantages of Rubber Seal
Temperature Resistance
Rubber seals can withstand extreme temperatures and variations. For instance, silicon rubber seals will withstand temperatures as low as -100 degrees Celsius and up to 310 degrees Celsius. The wide range makes rubber seals ideal for applications with massive temperature swings.
Comparative Durability
Rubber is more durable than other materials and forms an impervious airtight and watertight seal. More importantly, rubber is flexible and provides resistance in proportion to the pressure applied. Rubber seals also maintain integrity for a longer duration.
Highly Malleable
Rubber is easy to mold into different sizes and shapes used in a wide range of applications. O rings, U rings, and V rings are popular examples of rubber seals. Others are rotary oil seals, spring-installed seals, bearing isolators, and clearance seals.
Less Toxic
Most types of rubber seals are non-toxic in the environments they work. Rubber won't compromise the grooves or other components it contacts. It also won't degrade under heat, ethylene oxide, electron beams, steam autoclaving, or gamma radiation sterilization.
More Compatible
Rubber is compatible with many materials and can complement other substances to improve the seal's integrity. Rubber treatment can improve compression capabilities, tolerance to extreme temperatures, and overall longevity, and also prevent seal failure.
Different Grades and Colors
Rubber seals come in different grades, such as soft rubber, hard rubber, and everything in between. Some options, like thin gauge gasket sheets, are ideal for specialized application, while others are for general use.
