u shaped silicone gasket. In electrical applications, their non-conductivity properties make them perfect for insulating components. They even find usage in food and pharmaceutical industries due to their non-toxicity and ease of cleaning.
- The 22-32-7 oil seal is designed to fit shafts with a diameter of 22mm, housings with a bore of 32mm, and a width of 7mm. This specific size makes it suitable for a range of applications in machinery and equipment, including automotive engines, pumps, gearboxes, and hydraulic systems.
- Valve cover gaskets are typically made from a variety of materials, including rubber, silicone, and fiber reinforced materials
Corteco is a well-known brand in the automotive industry, supplying top-quality oil seals, including the first Simmerring® in 1929. The range consists of more than 7000 gaskets and more than 6500 OE-quality shaft and valve stem seals.
- The primary function of a cylinder head gasket is to create a tight seal between the cylinder head and the engine block. This seal is essential for several reasons. First, it prevents the mixing of coolant and engine oil, which can cause serious damage to the engine. Second, it ensures that combustion gases do not escape from the combustion chamber, which can lead to a loss of power and efficiency. Finally, it helps maintain the proper pressure within the engine, which is crucial for optimal performance.
In order to use the oil seal reasonably, the following points should be paid attention to:
Functions
Scrape off all the traces of dirt and old gasket from the engine and sump flanges with a paint scraper.

6. AMOUNT OF LUBRICANT: Seals perform better when lubricated but some machines will go through some dry spells. When this occurs using a leather or PTFE seal will be more beneficial as those type of seals can operate with less lubrication.
From this kind of standard immersion testing, one would expect that bisphenol-cured VDF/HFP/TFE fluoroelastomers would not give good service life as oil seals. Similar tests with other elastomers, such as HNBR, silicone, and acrylic rubbers, show less loss of elongation. However, it is found that, in actual service, FKM shaft seals6 have much longer service life than seals of the other elastomers. In a Japanese study of FKM lip seals, rear crankshaft seals from high-mileage automobiles (70,000–280,000 mi ie, 110,000–450,000 km) were collected and examined. No serious oil leakage was found when the seals were removed from the engines. Some deposits were found around the seal lip and on the garter spring holding the lip against the shaft. No surface cracks were found on the seal lip, and only minor crazing on the crankcase side of the flexure portion of the seal in some samples. The seal compositions were not noted, but most were probably VDF/HFP/TFE elastomers with 68–69% fluorine content.
As shown in Figure 1, sealing devices come in two types: contact and non-contact.
Oil seals are among the major contact type sealing devices.
