This refers to the component of the oil seal that makes contact with the shaft.
It is wedge-shaped to be pressed against the shaft surface and makes contact with the shaft to ensure sufficient sealing performance and suitability for operation at high peripheral speed.With minor lip

Table 3: Features of each seal type- One of the key advantages of metal-to-oil seals is their ability to withstand extreme pressure differentials. These seals are designed to maintain their integrity even when subjected to significant pressure differences, ensuring that oil remains confined within the system These seals are designed to maintain their integrity even when subjected to significant pressure differences, ensuring that oil remains confined within the system

metal oil seal. This is particularly important in applications where the pressure within the system can fluctuate significantly, such as in hydraulic systems or aircraft engines.
Polytetrafluoro-ethylene (PTFE - Teflon)
- When it comes to spark plugs, there are several different types to choose from. Each type has its own unique features and benefits, making it important to select the right spark plug for your specific needs.
- The RC7YC spark plug is designed to ignite the compressed fuel and air mixture in the combustion chamber, creating a controlled explosion that drives the pistons and ultimately powers the vehicle. This process relies on a precise timing and spark intensity, which is why it's important to choose the right spark plug for your engine.

Engine Oil Seal:
These seals are more commonly used in pumps, motors both electric & hydraulic, gearboxes & occasionally dirt wipers in hydraulic cylinders. They help protect shafts and bearings from dirt and harmful contaminants entering the internals of the application that they are fitted to, as well as prevent any leaks of lubricant.

Material Selection:
Automotive rubber gaskets are widely used in various vehicle systems for their flexibility, resilience, and sealing properties. These gaskets are employed in applications such as engines, transmissions, and exhaust systems, providing reliable sealing solutions to prevent fluid or gas leakage. The versatility and durability of automotive rubber gaskets make them essential components in maintaining the integrity and efficiency of vehicle systems.


With a helper holding the engine steady, remove the wedge supports, lower the engine and reconnect the mountings loosely.
An overview of the different standard types of oil seals and their main characteristics is shown below.
By far, nitrile is the most popularly used, but buyers who need seals for applications involving high-speed shaft rotation increased interest. Viton is another alternative for silicone and poly-acrylic because it’s more resistant to harmful chemicals and abrasion and works better in higher temperatures.
