- 1. Chemical Resistance 40mm rubber gaskets are renowned for their ability to withstand a wide array of chemicals, including acids, bases, solvents, and oils. This makes them ideal for use in harsh environments where exposure to chemicals is inevitable.
- E3 2022, the world's premier gaming event, showcased the latest advancements in technology, including a spotlight on the future of spark plug technology. As one of the most critical components in the automotive industry, spark plugs have undergone significant transformations over the years, and this year's E3 provided a glimpse into their next evolution.
- 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.

Oil seals are installed beside the bearing while the flexible lip is pressed against the rotating shaft. The casing pressing into the housing holds the seal in place. The sealing lip is essentially lubricated to minimize the risk of overheating due to the generated friction.
Meanwhile, rubber-cased oil seals are used under conditions where a metal-cased seal can fail (for example, because of thermal expansion). Unlike the metal-cased type, these seals do not rust. Moreover, they can seal a lightly damaged housing better than metal-covered seals since, in high temperatures, rubber can provide a more stable sealability.

The basic principle of an oil seal is fairly straightforward. It is installed adjacent to the bearing, with the flexible lip against the rotating shaft and the casing pressed into the housing to hold the seal in place. It’s important that the sealing lip is lubricated to prevent it from overheating as a result of any generated friction. It’s also crucial to understand which type of seal is appropriate for your particular machinery. Before selecting your seal, consider the environment, temperature, pressure and shaft speed of your machine, as well as the type of medium the seal will come into contact with during operation. These considerations will all determine the size, colour, and type of lip material or sealing element to choose, and whether it can be sealed in or sealed out.
The sealing element makes up the interior of the oil seal, and the materials commonly used are:

• ACM rubber
