MK/L seal has a dynamic lip which is shorter than the static one and it is used in cases of high rod misalignments and possible high pressure. On the dynamic side it has a multifunctional double lip which:
- mitigates any stick-slip effect (effect sticking seals) due to a fluid ring between the secondary lip and the main one
- blocks any external impurities
- counters the shrinking of the material at low temperatures
- works as a stabilizer
