To act as a physical barrier retaining the lubricating oil where it is bound to be.
After installing the new spark plugs, reassemble any components you removed to access them. Start the engine and listen for any unusual noises or vibrations. Take the vehicle for a test drive to ensure that the engine is running smoothly and that there are no misfires.Different types of rotary shaft seals are available in the market, including radial lip, axial lip, and mechanical face seals.
Despite being a great substitute for more expensive high temperature resistant materials, polyacrylate has a problem of poor water compatibility and cold flexibility.
Polyacrylate
Better heat, oil and chemical resistance than NBR
It is recommended for use in oil which contains load bearing additives such as EP gear oils

Furthermore, the axia spark plug is equipped with a strong metal shell that provides durability and protection for the internal components. This robust construction allows the spark plug to withstand the harsh conditions inside the engine and maintain optimal performance over time. The axia spark plug is also designed to be easy to install and replace, making it a convenient option for vehicle maintenance. Iridium, an element on the periodic table, is six times rarer than gold, yet its properties make it ideal for spark plug construction. Its high melting point ensures consistent performance even under extreme temperatures, a critical factor in modern engines that operate at higher compression ratios. The dual electrode configuration further stabilizes the spark and reduces voltage requirement, resulting in a more efficient and reliable ignition process.

A wheel hub oil seal, also known as a bearing seal, is a critical sealing device located between the wheel hub and the brake drum or disc. Its primary function is to prevent the ingress of dirt, water, and other contaminants into the wheel bearing while retaining the lubricating oil inside. This dual-purpose operation is crucial for maintaining optimal performance and preventing premature wear and tear. Regular maintenance of these spark plugs is crucial for optimal performance. Volkswagen recommends changing them every 100,000 miles. Neglecting this can lead to issues like rough idling, decreased acceleration, and even engine failure. Therefore, it's essential to adhere to the manufacturer's guidelines for replacement.
A number of variables must be considered when selecting oil seals. There are nine factors that designers and maintenance engineers must evaluate when oil seals are specified:
When selecting an oil seal, it is important to consider factors such as the type of fluid being sealed, the temperature and pressure ranges, and the speed at which the shaft or piston will rotate. This will help ensure that the seal is compatible with the specific requirements of the application and will provide the necessary level of protection.The primary function of a shaft oil seal is to retain lubricating fluids within the system while preventing the ingress of external contaminants. This is particularly important in high-speed applications where the loss of lubricant or the entry of contaminants could lead to rapid wear and damage to the equipment.
