Two types of piston seals are in use: Well-tried lip rings and u-cups, and double-acting seals which can be pressurized according to operating conditions. (The most common double acting piston seals are compact piston seals). Piston seals feature an interference fit on the inner diameter, while the dynamic movement occurs on the outer lip (outside sealing).
