Seals are designed to create a tight seal around the shaft by utilising a combination of lip geometry, surface tension, and lubrication. When the shaft rotates, the lip of the oil seal comes into contact with the shaft surface, creating a frictional force that generates heat. This heat helps to soften and conform the elastomeric material of the oil seal to the shape of the shaft, ensuring an effective sealing action.

In conclusion, shaft oil seals are essential components in machinery and equipment that help to prevent leaks, protect critical components, and ensure smooth operation. Their importance cannot be overstated, and proper selection, installation, and maintenance are key to maximizing their effectiveness and prolonging their lifespan. With the right seals in place, machinery can operate efficiently and reliably, delivering optimal performance and productivity.
Major global spark plug suppliers, such as NGK Spark Plug Co., Ltd., Bosch, Denso Corporation, Federal-Mogul LLC (now part of Tenneco), and Champion Spark Plug, have been at the forefront of innovation and technology advancement. These companies not only provide standard spark plugs but also cater to specialized needs, including high-performance racing engines and environmentally friendly hybrid vehicles.

3. TEMPERATURE: Similar to the pressure level, you need to know what temperature your machinery can operate at. You need to choose a seal that can withstand the heat or cold. PTFE have the widest rang of temperature, making them a safe option when you are uncertain of the range.
Next, remove the old spark plugs using the spark plug socket and ratchet An oil seal, also known as a shaft seal, is a mechanical gasket that is used to prevent the leakage of fluids such as oil, water, or chemicals. They are typically used in rotating equipment, such as engines, pumps, and gearboxes, to prevent the escape of lubricants and to keep out contaminants.If the drive gear has slanting teeth, they may cause the rotor arm to turn. If it does, mark its new position to aid refitting
Orient your seal the same way as the initial install.The sealing lip should face the lubricant that requires sealing.The second lip on a double lip oil seal is intended as a dust lip. The seal must be installed at a 90°, or perpendicularly, to both the shaft and housing bore. This is an issue in cases where the housing does not have a counterbore or shoulder the seal can seat up against.
