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.
Over time, the seal lip(s) will wear a shallow groove into the shafting due to the pressure the seal imposes upon it. Visible scoring on the shaft indicates a genuine possibility that the seal will not perform as well as intended. The potential for lubricants leaking out and particulates working their way through the seal drastically increases when placed over a worn location.

One important factor to consider when choosing spark plugs for your MK7 GTI is the heat range. The heat range of a spark plug refers to its ability to dissipate heat away from the tip of the spark plug. Choosing the right heat range for your MK7 GTI is important to ensure optimal performance and longevity of the spark plugs.
These are now the current and most recent innovation that is taking over from the HID and Halogens. The LEDs employ the diodes technology where they produce light when electric current excites their electrons. They require low power and energy and still produce brighter light than halogen headlights which also leads to LEDs’ longer life-span. Their diodes can be manipulated into various shapes providing unique configurations. With LED technology, the vision is much improved and more focused. Although the initial cost of HID and halogen bulb is less than LEDs, the operational and maintenance costs of LED are significantly lower. LEDs, having a longer life, reduce maintenance and lamp replacement cost. Because LEDs need to be replaced less frequently, the owner spends less on new lamps and the labor needed to change them. LEDs also consume less energy; thus the overall cost of a LED system can be significantly lower than that of conventional lighting systems.
The proper functioning of seal oil pan, oil seal turbo, and oil gasket seal is crucial for the performance and longevity of the engine. High-quality seals are essential to prevent oil leaks, maintain proper lubrication, and protect the engine components from wear and damage. When selecting these seals, it is important to prioritize quality, durability, and compatibility with specific engine models to ensure optimal performance and reliability.

It is important for the spark plug to produce a strong and consistent spark in order for the combustion process to be efficient. Over time, the spark plug can become worn or dirty, which can affect its performance. This is why it is recommended to regularly inspect and replace spark plugs as needed to ensure optimal engine performance.
