S-DUO Common materials used in oil seals include nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene, etc. When selecting the material of the oil seal, the compatibility of the material with the working medium, the adaptability to the working temperature range and the ability of the lip to follow the rotating shaft at high speed must be considered. When the oil seal is working, the temperature of its lip is higher than the working medium temperature by 20~50°C. Attention should be paid when selecting the oil seal material. The working range of the oil seal is related to the material used for the oil seal: the material is nitrile rubber (-40~120°C), Aggreko rubber (ACM) -30~180°C, fluorine rubber (FPM) -25~300°C.


In this way, selecting the appropriate oil seal will lead to machine design that is economically superior!
An oil seal normally consists of three basic components: the sealing element, the metal case and the spring. The purpose of the sealing element is to stop the fluid from leaking between the shaft and housing. The metal case will give rigidity and strength to the seal while it is being held in the bore or recessed groove. The garter spring ensures constant pressure and maintains the radial force to the shaft, flattening the sealing edge to a defined width. The garter spring maintains the radial force exerted by the sealing lip around the shaft surface. All materials must be selected depending on the environment in which the oil seal will function.
When selecting a natural rubber gasket for your specific application, there are several key factors to consider. The first is the hardness of the gasket, which is typically measured on the Shore A scale. A softer gasket (lower Shore A hardness) is more flexible and better suited for applications where the sealing surface is uneven, while a harder gasket (higher Shore A hardness) provides better resistance to compression and extrusion.


Natural rubber gaskets are essential components in a variety of industries, from automotive to plumbing, and play a crucial role in preventing leakage and ensuring airtight seals. Made from high-quality natural rubber, these gaskets are known for their durability, flexibility, and resistance to a wide range of temperatures and environmental conditions. In this article, we will explore the benefits of natural rubber gaskets and the key factors to consider when choosing the right gasket for your specific application.
An overview of the different standard types of oil seals and their main characteristics is shown below.
Oil Seal Materials

Like any element of the engine, oil seals are subject to wear. Over time they can lead to possible leaks of lubricating liquid.
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.
In addition to withstanding high pressures, oil seals must also be able to withstand the harsh conditions often found in industrial settings. This includes exposure to oil, chemicals, heat, and vibration, which can all contribute to the degradation of the seal over time. Proper selection of materials and regular maintenance are essential for ensuring the longevity and reliability of high-pressure oil seals.

7mm spark plug wire. This means that 7mm spark plug wires can withstand the harsh conditions of the engine bay and continue to function effectively for thousands of miles.
Lubricant can be retained in the space between the main lip and the minor lip.
