- One of the key functions of the auto parts spark plug is to ignite the air-fuel mixture at the right time and ensure proper combustion. This is achieved by delivering a high voltage electrical current from the ignition system to the spark plug, which then generates a spark to ignite the fuel. A properly functioning spark plug will ensure that the engine runs smoothly and efficiently.

- Firstly, oil seals are essential for maintaining proper lubrication within the motor. Lubrication is crucial for reducing friction between moving parts, which can cause excessive wear and tear over time. Without adequate lubrication, the motor's components may become damaged or fail prematurely, leading to costly repairs or even replacement of the entire unit. By preventing oil leakage, oil seals help to ensure that the motor's internal parts remain well-lubricated, promoting smooth operation and extending the lifespan of the machine.

- Spark plug wires, also known as ignition wires or high-tension leads, are responsible for transmitting the high voltage from the distributor or ignition coil to the spark plugs. They ignite the air-fuel mixture in the combustion chamber, thereby propelling the vehicle forward. The diameter of these wires, in this case, 7mm, is a critical factor that influences their effectiveness.

- Do not top up engine oil and do not start the engine until four hours after assembly. This is advised by both Elring and Victor Reinz to allow the new oil seals to form to the shaft.
- 1. Automotive industry High temperature rubber gaskets are used in engine compartments, exhaust systems, and transmission systems to provide sealing against heat and chemicals.
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.
Shaft and Bore Tolerance
The edge of the metal is finely ground after seal manufacture in a centerless grinder to enable an interference fit in the oil seal housing. A slight chamfer on the outer diameter (OD) of the seal is desirable for easy assembly. The sealing lip is prepared by buffing, grinding or cutting away the rubber flash which occurs at the sealing edge. A fine sealing edge creates sufficient pressure on the shaft to minimise spring load, leading to lower friction whilst maintaining effective seal performance. The garter spring plays an important role in the efficiency of the oil seal. If its tension is too high, heat will be generated between the sealing lip and the shaft, and result in rapid wear of the lip. If too low, the spring will be ineffective and the sealing lip will be worn away leading to leakage of the fluid.
One of the key benefits of floating oil seals is their ability to provide a secure and reliable seal even in high-pressure environments. Unlike traditional seals that rely on compression to create a seal, floating oil seals utilize a unique design that allows them to float on the oil and adjust their position as needed to maintain an effective seal. This design not only enhances the reliability of the seal but also helps to prolong the lifespan of the seal by reducing wear and tear.

5. TYPES OF FLUID: Numerous oil seals can interact with oils, fuels, grease, water and more. However, know exactly what type of fluid the rotary shaft seal will be in contact with will ensure the longevity of the seal and the machinery.
Make sure that the new gasket is clean, and confirm which way round it fits. The upper side is usually marked 'top', 'haut' or 'oben'.

Oil seals made of HNBR are characterised by excellent properties that include high resistance to mineral oils with additives, low steam and gas permeability, good cold flexibility down to -30 °C depending on type, good ozone resistance and friction resistance. HNBR seals withstand heat up to 150°C.
