- In today's digital era, the role of spark plug suppliers has become more dynamic. Many now offer online platforms for easy ordering and quick delivery, along with comprehensive technical support and resources for diagnostics and repair.
Once you have selected the most suitable seal available, considering the environment, temperature, shaft speed, pressure, lubrication availability, as well as the size, of course, the seal should be stored adequately and then fitted properly. Here are a few suggestions that could help:-
The sealing element makes up the interior of the oil seal, and the materials commonly used are:
Also, Viton has the widest range of resistance to chemicals. It’s resistant to several chemicals like silicone oil & grease, mineral & vegetable oil, aliphatic, chlorinated hydrocarbons, methanol fuels, and so many more.
To act as a physical barrier retaining the lubricating oil where it is bound to be.
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.

Most ERIKS oil seals, such as the types M, MST, R and RST, are made of NBR as standard.
Oil seals, also known as oil lip seals, dirt seals, grease seals, shaft seals, or rotary seals, are used to fill the gaps between stationary and revolving parts of the equipment. They are designed to prevent the leakage of fluids from the machinery and inhibit contaminants from reaching these fluids. They contribute to the longevity and reliability of the equipment like engines and gearboxes in industrial equipment. This post discusses the importance of oil seals, the different types of materials that are used in the manufacturing of oil seals and many more.
