- Nitrile Rubber (NBR): This is the most frequently used material for sealing elements, boasting good heat resistance properties and resistance to salt solutions, oils, hydraulic oils, and gasoline. Its recommended operating temperature range is from -40 to 248°F (-40 to 120°C). Nitrile functions adequately in a dry environment but only for intermittent periods.
- cold tolerance is relatively insignificant.
Polyacrylate Oil Seals - Mostly selected for automotive and transmission uses, polyacrylate seals are able to withstand fuel, oil, ozone, sunlight and weather when used. With cars exposed to all these different fluids and elements, they are the perfect choice. However, they should not be used in low temperatures, as their flexibility weakens when cold.

Oil seals normally consist of three basic components: the sealing element, the metal case, and garter spring.
PTFE oil seals
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.
Double Lip Oil Seals

In conclusion, spark plugs are a critical component of any internal combustion engine, as they are responsible for igniting the air-fuel mixture and powering the vehicle. Regular maintenance and replacement of spark plugs are essential to ensure optimal engine performance and efficiency. By choosing the right type of spark plugs and properly installing them, vehicle owners can enjoy a smoother and more reliable driving experience.
As an example, this oil seal has a part number that corresponds to a Shaft Size of 3”, a Bore Size of 4”, a Width Size of 0.625”, a Style of TB2, and is made of Viton material. Conversely, the same size oil seal in Metric has a Shaft Size of 76.20 mm, a Bore Size of 101.60 mm, and a Width Size of 15.88 mm.
