The use of water in high-pressure jet cutting and machining requires seals capable of sealing reciprocating and rotating shafts with minimal leakage. Both Morrison and Parry seals are studied analytically to determine the geometric parameters influencing their behavior in water. Limited experimental evidence supports the findings. In particular, the Morrison seal is most appropriate for use with oil, while the Parry seal shows greater potential for sealing water.
