Some aspects to consider when selecting this component are:
Take extra care with a light alloy block or head. It is vital to avoid scratching the machined surface.
PTFE, which is used in the well-known brand Teflon®, is less commonly used, but it is the preferred material for specific rotating seals in the chemical, food and pharmaceutical industries. This material is notable for having a very low frictional resistance and the best chemical resistance. It can also withstand a very wide range of temperatures in these types of seals; -80 ˚C to 200 ˚C. The shafts on which oil seals with PTFE lips are used require a harder and finer finish. Something like an axle sleeve can also be used to meet this requirement.
- A spark plug O-ring is a small but essential component in the operation of a vehicle's engine. This tiny ring plays a crucial role in maintaining the seal between the spark plug and the engine block, preventing any oil or debris from entering the combustion chamber.

- The LS3 Valve Cover Gasket, a seemingly insignificant component in the grand scheme of a high-performance engine, plays a pivotal role in ensuring optimal functionality and longevity. This small but crucial element is specifically designed for Chevrolet's LS3 engine, a powerhouse found in various vehicles including Corvettes, Camaros, and Holden Commodores.
- Another important consideration when selecting an oil seal is its compatibility with the oil being used in the machine

1. The oil seal consists of a metal ring as the inner skeleton which provides the structural stability to the oil seal.


In addition to the installation procedure, our specialists and suppliers would also like to draw your attention to some cases that occur around oil seals.
