All are fitted with a spring to preload the sealing lip. All these types are for non-pressurised or low-pressure applications up to 0.5 bar for diameters of a limited size. For diameter of 500 mm or more, the maximum pressure is 0.1 bar. For higher pressures, special types or PTFE lip seals can be used.

Multiple materials and compounds are used to make oil seals. Some of the oldest materials still used today include felt and leather compounds. However, the trend in mass production has experienced a shift towards synthetic elastomers or rubber.
