Common materials used in oil seals include nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene, etc. When selecting the material of the oil seal, the compatibility of the material with the working medium, the adaptability to the working temperature range and the ability of the lip to follow the rotating shaft at high speed must be considered. When the oil seal is working, the temperature of its lip is higher than the working medium temperature by 20~50°C. Attention should be paid when selecting the oil seal material. The working range of the oil seal is related to the material used for the oil seal: the material is nitrile rubber (-40~120°C), Aggreko rubber (ACM) -30~180°C, fluorine rubber (FPM) -25~300°C.

1. Criteria for selecting oil seals

In addition to withstanding high pressures, oil seals must also be able to withstand the harsh conditions often found in industrial settings. This includes exposure to oil, chemicals, heat, and vibration, which can all contribute to the degradation of the seal over time. Proper selection of materials and regular maintenance are essential for ensuring the longevity and reliability of high-pressure oil seals.
