  • 1. Criteria for selecting oil seals

  •  

  • The primary function of an oil seal is to create a tight seal between two moving parts, such as a shaft and housing, while allowing for relative motion. This is achieved through the use of a flexible material, such as rubber or synthetic elastomers, which conforms to the surface of the moving part and creates a seal. The seal is typically reinforced with metal or other materials to provide additional strength and durability.
  • Benefits of Using Thick Rubber Gaskets
  • In conclusion, spark plug suppliers are integral to the automotive industry, driving innovation, improving efficiency, and contributing to the evolution of cleaner and more efficient engines. Their commitment to quality, R&D, and customer-centric services underscores their importance in this dynamic sector. As the world moves towards electric and hybrid vehicles, these suppliers continue to adapt, ensuring they remain a critical link in the automotive value chain.

  • Polyacrylate (ACM) Oil Seals

  • A square rubber gasket is a vital component in various mechanical applications, providing a seal between two surfaces to prevent leakage or contamination. These gaskets are commonly used in machinery, engines, piping systems, and automotive applications.

  • Auto Gasket: Essential Sealing Components in Vehicles

  • Oil seals come in a vast range of materials and compounds. Even older materials, such leather, are still used today. Nitrile is among the most common materials for oil seals but is slowly losing ground to PTFE, which is gaining popularity due to its effectiveness in high-speed applications. 

  • The shaft surface to be in contact with the lip should be finished to
    0.1 to 0.32 μmRa and 0.8 to 2.5 μmRz
    and the lead angle to no greater than 0.05°. (There is a risk that the lead marks will impede the sealing performance of the oil seal: see Figure 5.)

  • Sealing lip

  • The design and material of a shaft oil seal are crucial factors in determining its effectiveness and durability. High-quality seals are made from durable materials that can withstand high temperatures, pressures, and speeds. They are also designed to maintain a tight seal against the shaft while allowing for smooth rotation without excessive friction or wear.


  • Vulcanizates of several fluoroelastomers, listed in Table 14.1, were exposed to a standard 5W-30 engine oil, ASTM Service Fluid 105, for up to 6 weeks at 150°C (302°F).5 The oil was changed weekly, but was not aerated. Retained elongation was measured after exposure for 1, 2, 3, and 6 weeks; data are shown in Fig. 14.3. The results indicate that bisphenol-cured FKM-A500 VDF/HFP copolymer, FKM-B600 VDF/HFP/TFE terpolymer, and peroxide-cured FEPM-7456 TFE/P/VDF terpolymer lost most of their original elongation over the course of the test exposure, indicating considerable additional cross-linking occurred by reaction with amine- and phenol-containing oil additives. The other fluoroelastomers showed better retention of elongation, being much less susceptible to additional crosslinking. Note that FEPM-7456 contains a high level of VDF (about 30%), while FEPM-7506 contains a relatively low VDF level (10–15%) to serve as cure site for bisphenol curing. The other FEPM types contain no VDF.
