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.

In addition to its antimicrobial properties, potassium metabisulfite also acts as an antioxidant. It helps to prevent oxidation, a process that can alter the color, taste, and nutritional value of food products. For example, when fruits are cut and exposed to air, they tend to brown due to enzymatic oxidation. Adding potassium metabisulfite can slow down this process, keeping fruits looking fresh and appealing for longer. This is particularly beneficial in the production of dried fruits, where appearance plays a crucial role in marketability.
