1. What are FKM Oil Seals?

FKM oil seals are made from fluoroelastomer, a synthetic rubber known for its excellent resistance to heat, chemicals, and weather. These seals are often used in extreme conditions, making them ideal for high-performance applications.

2. What are TC Oil Seals?

TC oil seals, or thermoplastic elastomer seals, are made from a combination of plastic and rubber materials. They are designed to provide good sealing properties, flexibility, and durability under moderate conditions. TC seals are versatile and cost-effective, making them suitable for various applications.

3. What are the Key Differences Between Wholesale FKM and TC Oil Seals?

Here are some key differences to consider when comparing these two types of oil seals:

  1. Temperature Resistance: FKM oil seals can withstand higher temperature ranges (up to 200°C) compared to TC oil seals, which are generally effective up to 100°C.
  2. Chemical Resistance: FKM seals are more resistant to aggressive chemicals, oils, and solvents, making them the preferred choice in harsh environments. TC oil seals have moderate chemical resistance.
  3. Cost: Typically, FKM oil seals are more expensive than TC oil seals due to their superior properties and production costs.
  4. Application Suitability: FKM seals are ideal for automotive, aerospace, and chemical industries, while TC seals are often used in household appliances, medical devices, and automotive applications where conditions are not as extreme.

4. Which One is Better for Your Application?

The choice between Wholesale FKM and TC oil seals depends on the specific needs of your application. If you are dealing with high temperatures and aggressive chemical exposure, FKM oil seals would be the better option. Conversely, for general-purpose use with moderate conditions, TC oil seals can be a cost-effective solution.

5. Where to Find Quality Seals?

When searching for a reliable source, it’s essential to choose a reputable wholesale FKM TC oil seal supplier. These suppliers can provide you with high-quality seals that meet industry standards and specific requirements for your projects.
