    Fluoroelastomers, also known as Viton, are used in hydraulic cylinder seal kits for applications requiring resistance to high temperatures and aggressive chemicals

    hydraulic cylinder seal kit material. Fluoroelastomer seals are known for their excellent chemical resistance, high temperature stability, and low compression set. These seals are commonly used in aerospace, automotive, and other industries where extreme conditions are present.
    The importance of oil seals in hydraulic systems cannot be overstatedoil seal hydraulic. A faulty or worn-out seal can lead to fluid leaks, causing a drop in system pressure and reduced performance. Moreover, the ingress of contaminants can damage sensitive components, leading to costly repairs or even complete system failure. Therefore, regular inspection and timely replacement of oil seals are essential for maintaining the overall health and longevity of hydraulic systems.

    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.
