Rod seals
In hydraulic cylinders, rod seals are used as fluid seal. These seals prevent liquid leakage from the cylinder to the outside, and are mounted externally to seal the cylinder rod.
Superior Seals for Peak Performance
At Advanced Sealing Technology we have a wide range of rod seals. These seals stand for the ultimate protection against the ingress of media into the system, low frictional resistance, compact dimensions and easy installation. Our seals meet all the important requirements of our customers. Hydraulic rod seals are usually produced in PTFE compounds based material or in polyurethane. This means that our seals can be used in almost all media. If you would like to know more about the possibilities of our seals, please feel free to contact us or request a no-obligation quote below.
