Maintenance and Replacement of Oil Seals
Oil seals come in various shapes to fit the machines and substances to be sealed.
Figure 2 shows the structure and the names of the various components of the most typical oil seal.
The functions of the various components are also indicated in Table 1.
Bauerle and Bruhnke7 found that aeration reduces the effect of oil additives on fluoroelastomer properties. Some of their data is reproduced in Fig. 14.4,5 showing the effect of aeration of an SF-grade 5W30 oil on the retention of elongation of a VDF/HFP copolymer (FKM-E430), a VDF/HFP/TFE terpolymer (FKM-B600), and a VDF/PMVE/TFE fluoroelastomer (FKM-GFLT). The HFP-containing polymers show much better retention of properties with aeration.

Automotive applications also rely on square rubber gaskets for a wide range of sealing requirements. From sealing doors and windows to engine components and exhaust systems, these gaskets play a crucial role in maintaining the safety and performance of vehicles.
What is Oil Seal
Table 2 a): Common types of oil seals (with spring)
Oil gasket seals are used in various parts of the engine, including the valve cover, cylinder head, and oil filter housing. These seals are designed to prevent oil leaks and maintain the integrity of the engine components. The oil gasket seal ensures that the engine remains properly lubricated and free from oil leaks, contributing to its overall efficiency and reliability.
Fit the new gasket to the cover or head — whichever the old gasket was fixed to.


A number of variables must be considered when selecting oil seals. There are nine factors that designers and maintenance engineers must evaluate when oil seals are specified:
The first step in installing oil seals is to clean the surface where they will be placed. Dirt, debris, and other contaminants can cause the oil seal to become damaged or misshapen, leading to leaks. Clean the surface with a solvent or soap and water, and make sure it is completely dry before installing the oil seal.
Overall, neoprene foam gaskets are a reliable and cost-effective solution for sealing and insulation applications in a wide range of industries. Their resilience, sealing properties, insulation capabilities, and versatility make them a preferred choice for manufacturers, engineers, and maintenance professionals who depend on high-quality gaskets to ensure the performance and longevity of their equipment.
