Spark Plug Automotive: Enhancing Performance and Reliability
Type B Oil seals

These seals are designed to fit snugly around the shaft of the machine, preventing oil from leaking out while also keeping dirt, dust, and other contaminants from entering.

oil seal in motor. They are specially engineered to provide a tight seal that can withstand the rigors of daily use. Without proper oil seals, the motor can suffer from oil leaks, reduced efficiency, and ultimately, complete breakdown.
NBR rubber is above all resistant to oils, especially hydraulic oils, lubricants, petrol and other aliphatic hydrocarbons, diluted acids and lyes. Good physical values such as high friction resistance and ruggedness and good temperature resistance (-25 °C up to +120 °C, in part to -40 °C) give this natural rubber a wide range of uses.

The temperature range of the mechanism in which the seal is installed must not exceed the temperature range of the seal elastomer.
