The first material that we are going to look at is Nitrile Buna- N 70 or NBR for short.
-15 °C to + 180 °C
Jam the flywheel ring gear to prevent the engine turning while you undo the crankshaft pulley bolt. - When the thermostat gasket fails, it can lead to a multitude of problems. Leaks in the gasket can result in coolant loss, potentially causing the engine to overheat. Overheating, if left unchecked, can lead to severe damage such as blown head gaskets, warped cylinder heads, or even complete engine failure. Conversely, if the thermostat is not functioning correctly due to a faulty gasket, it might restrict coolant flow, leading to inefficient heating or, conversely, excessive cooling, impacting fuel efficiency.
- The spark plug O-ring is typically made from a durable and heat-resistant material such as rubber or silicone. This material is able to withstand the high temperatures and pressures that occur inside the engine during combustion. Without the O-ring, there would be a risk of oil leaking into the combustion chamber, which could lead to engine misfires and reduced performance.

The MK7 GTI is a popular choice among car enthusiasts for its performance and style. One important component of the MK7 GTI that is often overlooked is the spark plugs. Spark plugs play a crucial role in the ignition process of an engine, and having the right spark plugs can make a big difference in the performance of your car.
These problems can be overcome through a better understanding of the types of sealing materials available, redefined selection procedures and the consistent application of sound replacement and maintenance practices.
Nitrile Oil Seals - Nitrile oil seals, which is the commonly used term for acrylonitrile-butadiene rubber seals, is a very good general-purpose option due to the flexibility of use across a variety of components. The resistance is strong against fats, hot water, gasoline, mineral oils, grease and animal oils, making them the most often-used oil seals. They do not have a wide temperature range, making them a poor choice for machinery that can see extreme changes in temperature.


ptfe oil seal. This makes them suitable for use in applications where other types of seals may be damaged by exposure to chemicals.
Leather
Recommended for abrasive applications
Good running properties, due to the impregnated seal lip
Can be used on shafts which have a surface roughness outside the range for rubber seals
Not suitable for water
An overview of the different standard types of oil seals and their main characteristics is shown below.
Engine oil seals are vital components in the automotive engine system, designed to prevent the leakage of lubricating oil and the ingress of contaminants. These seals play a critical role in maintaining the proper lubrication of the engine components, including the crankshaft, camshaft, and other critical parts. Engine oil seals contribute to the efficiency and longevity of the engine by preventing oil leaks and ensuring optimal performance.
