- Chemical resistance
- Regular maintenance and inspection of the spark plug are also essential to ensure proper engine operation. Over time, the spark plug can become fouled or worn out, leading to poor engine performance, misfires, and potential engine damage. By inspecting and replacing the spark plug as needed, you can keep your GY6 engine running smoothly and reliably.
Duplex Oil Seals
An oil seal is designed to perform three major functions: to prevent lubricants from leaking outside the seal even under high pressure, to act as a barrier to retain the lubricating oil, and to prevent dirt and other contaminants from entering the unit.
When the engine is running, the ignition coil receives a signal from the engine control unit to fire at the correct time. The coil then rapidly builds up a magnetic field within the primary winding when the signal is received, and when the signal is cut off, the magnetic field collapses rapidly, inducing a high voltage in the secondary winding. This high voltage is then sent to the spark plug, where it jumps the electrode gap, igniting the air-fuel mixture in the combustion chamber.
- The Indispensable Role of Rubber Flange Gaskets in Industrial Applications
Seals, including oil seals, have undergone a great development in recent years and are totally unlike the original product. PTFE has taken over the oil seals market for modern engines mainly because traditional oil seals started causing more and more problems. Such as evaporation of chemical plasticisers from the elastomeric material, which eventually caused engine oil leakage. Now, the focus is more on durability and frequency of servicing.
- The crankshaft oil seal is a critical component in an engine that helps to prevent oil from leaking out of the crankshaft housing. This seal is typically made of rubber or silicone and is located at the front or rear of the engine where the crankshaft exits the engine block.
Among the most common causes of oil seal failure are:
Regular inspection and maintenance of auto gaskets and head gaskets are essential to identify signs of wear, damage, or leakage. Proper replacement of worn or damaged gaskets is crucial for maintaining the integrity and performance of the vehicle's systems. Adhering to recommended service intervals and using high-quality replacement components are essential for optimizing the performance and longevity of the vehicle's gaskets.


Material Code ISO 1629
When selecting a 40mm rubber gasket for a specific application, it is important to consider factors such as the operating temperature, pressure, and chemical compatibility to ensure optimal performance and longevity. Additionally, the gasket should be installed properly following manufacturer recommendations to ensure a leak-proof seal.

How to Choose the Right Oil Seal
However, rubber-cased seals do have limitations. For example, during installation, shear stresses can build up between the seal and housing wall, causing the seal to release itself.

5. Keep it clean
In conclusion, oil seals are critical components in ensuring the proper functioning of machinery and equipment. By selecting the right seal based on material, design, size, and operating conditions, users can prevent oil leaks, reduce maintenance costs, and prolong the life of their equipment. With a wide range of options available, it is essential to choose a high-quality seal that meets the specific requirements of the application.
