Product Description NBR Material: Being second only to butyl rubber in terms of airtightness, NBR can be used under 120 degrees for a long time.Besides that, it possesses excellent oil resistance, wear resistance and tear resistance. (Word of attention: this material is semi-conductor rubber and can't be used for insulation products.) Therefore, it is often used on aotomobile, mechanical rubber hose, sealing element, cable sheath and sponge products. In order for you to understand its properties better, here is a form listing the pros and cons and applicable temperatures. Advantages of oil seal: Since oil seal has a rather simple structure, it requires less technology to produce them. In addition, it also has good wear resistance and oil resistance, good sealing performance and long service life. It has certain adaptability to shaft vibration, eccentricity and high-speed rotation. It can be easily assembled, disassenbled and fixed. More importantly, you can buy them at a very reasonable price. Precautions for using oil seal: Conduct a comprehensive inspection of the mechanical seal to see whether the pipeline and various auxiliary devices are safe and meet the basic requirements. Before using the oil seal, please conduct static pressure test to see if there is oil leakage. Before using the oil seal, please ensure that the liquid in the sealing cavity is full. After opening it, please don't worry if there is a slight oil leakage. Observe for four hours to see if the oil leakage is serious. If the oil leakage is not getting better, you should stop immediately to conduct inspection.
