In automotive applications, the proper functioning of oil seals is crucial for maintaining the performance and longevity of critical components. Trailer hub oil seals and Tora oil seals, among others, are essential for preventing oil leakage, minimizing friction, and protecting internal components from wear and damage. High-quality oil seals contribute to the overall efficiency, safety, and reliability of vehicles and machinery.
Auto spark plugs are critical components in the ignition systems of internal combustion engines in vehicles. These plugs play a pivotal role in igniting the air-fuel mixture within the engine cylinders, initiating the combustion process that powers the vehicle. High-quality auto spark plugs are essential for ensuring efficient fuel combustion, optimal engine performance, and reduced emissions, directly impacting the overall efficiency and environmental impact of the vehicle.

All are fitted with a spring to preload the sealing lip. All these types are for non-pressurised or low-pressure applications up to 0.5 bar for diameters of a limited size. For diameter of 500 mm or more, the maximum pressure is 0.1 bar. For higher pressures, special types or PTFE lip seals can be used.
Quality Assurance and Compliance: Ensuring Reliable Sealing Solutions
Among the most common causes of oil seal failure are:

The best seal performance is achieved when close shaft and bore tolerances are present. Other factors include shaft eccentricity, end play and vibration.
NBR rubber is above all resistant to oils, especially hydraulic oils, lubricants, petrol and other aliphatic hydrocarbons, diluted acids and lyes. Good physical values such as high friction resistance and ruggedness and good temperature resistance (-25 °C up to +120 °C, in part to -40 °C) give this natural rubber a wide range of uses.
Cassette seals are designed to maximise grease or oil retention and protection against liquid or solid contaminants. These seals are provided with their own bushings in which dirt is kept out and oil/grease kept in by a multi-lip seal.
