Oil seals are called rotary shaft seal or radial lip also.
- Oil seals, often made from high-quality rubber compounds or synthetic materials, are designed to prevent the leakage of lubricants while inhibiting the ingress of contaminants. The 8 in the name likely refers to the percentage of oil-resistant material used in the seal's construction, enhancing its ability to withstand exposure to various oils and lubricants without degradation.
- Installation of the F7RTC spark plug is relatively straightforward, although it's crucial to follow the manufacturer's guidelines for the specific vehicle. Regular maintenance, such as checking and replacing worn-out spark plugs, is essential to maintain peak engine performance and prevent potential issues like misfires, reduced fuel efficiency, or engine damage.
- Maintenance is another critical aspect of spark plug use

Nitrile is the most widely used rubber (elastomer) and it’s recommended as the best for almost all standard applications. This is solely due to the fact that nitrile has some intrinsic properties, such as low cost and compatibility with most environments. Some of the general applications of nitrile are non-latex gloves, automotive transmission belts, footwear, gaskets, synthetic leather, hoses, o-rings, and oil seals.
- Probably the least appealing solution is to either replace or refinish the shafting. In some cases, this is not possible; in others, it could benefit the application in the long term.
Dechengwang provides a full line of seal types, including PTFE seal, which is recognized as the best seal and the future of the seal industry. Amongst all other PTFE component manufacturers, Dechengwang stands out with unique products and services, as well as outstanding manufacturing capabilities.

Oil seals are made from multiple compounds and materials. Some of the oldest, still in use today, are leather and felt compounds. The trend in mass production, however, has seen a move towards synthetic rubber or elastomers. Nitrile is by far the most popular material but developments in PTFE have created a surge of interest in buyers needing seals for high-speed shaft rotation applications. Viton is taking over from the polyacrylic and silicone, as it works better in high-temperature applications and has a high-resistance to abrasion and harmful chemicals.


Silicone Oil Seals - Designed to absorb lubricants in order to lessen wear and friction, silicone rotary shafts also offer high thermal resistance and a large temperature range. But, they do not handle abrasions well or interact with oxidized oils.
