　　“Which is better rubber or metal oil seal?” The answer, as with many things in engineering, is: “It depends.” Both types oil seal have their advantages and disadvantages, and the best choice often depends on the specific application.

　　Rubber Oil Seals

　　Rubber oil seals are widely used due to their flexibility and durability. They can easily conform to irregular surfaces and maintain a tight seal, making them ideal for applications where the mating surfaces may not be perfectly smooth or flat.

　　1. Advantages: Rubber oil seals are resistant to a wide range of temperatures and chemicals. They are also relatively inexpensive and easy to replace, making them a cost-effective choice for many applications.

　　2. Disadvantages: However, rubber oil seals can degrade over time, especially when exposed to certain chemicals or extreme temperatures. They may also be prone to wear and tear, especially in applications involving high-speed rotation or heavy loads.

　　Metal Oil Seals

　　Metal oil seals are known for their strength and durability. They are typically used in high-pressure applications where a strong, rigid seal is required.

　　1. Advantages: Metal oil seals can withstand higher pressures and temperatures than rubber seals. They are also less likely to degrade over time, making them a good choice for long-term applications.

　　2. Disadvantages: However, metal oil seals can be more expensive and harder to install than rubber seals. They also require a smoother mating surface to form a tight seal, which may not be possible in all applications.

　　Both rubber and metal oil seals have their place in the world of engineering. The key is to understand the specific requirements of your application and choose the seal that best meets those needs.

　　Oil Seal is to prevent the leakage of lubricants, such as oil or grease, and to keep out contaminants that can cause damage or wear to rotating or reciprocating parts. For product details, please contact NQKSF seals factory.
