Oil seals can be made from various materials, including rubber, silicone, and polyurethane. The choice of material often depends on the operating conditions such as temperature, pressure, and the type of lubricant being used. For the 50x65x8 oil seal, nitrile rubber (NBR) is commonly utilized due to its excellent oil resistance and durability in a range of temperatures.

Water treatment typically involves several stages, including coagulation, sedimentation, filtration, and disinfection. The coagulation process involves adding chemicals to the water that bind with impurities, forming larger particles called flocs. During sedimentation, these flocs settle at the bottom of the treatment tank, allowing clearer water to be collected. The next step, filtration, involves passing the water through layers of material such as sand, gravel, or charcoal to remove remaining particles and microorganisms. Finally, disinfection is crucial in killing any pathogens that might be present in the water. Common disinfection methods include chlorination, ultraviolet light treatment, and ozonation.
