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.

Moreover, drain covers protect the drainage systems from costly blockages. Roads are often littered with debris, including leaves, dirt, and litter. If these materials were to enter the drainage system, they could cause significant clogs, leading to the need for expensive repairs and maintenance. By adequately covering drainage points, drain covers serve as a barrier against this debris. Regular maintenance of drain covers is also essential; any damages or misalignments should be addressed promptly to ensure optimal functioning.
