Modern sealing system are composed of various individual components (e.g. sealing ring, supporting ring, wiper, etc.), each of which has its corresponding purpose. Adapting them properly to the particular operational requirements has a decisive effect on how long hydraulic cylinders can operate without faults. Among other things, this means that seals that provide proper sealing under high pressures are not necessarily suitable for low pressures.



AHP Merkle‘s years of experience in the development and production of hydraulic cylinders resulted in the selection of seals that cover the widest range of applications possible.



The compatibility of the hydraulic fluid with the seal material has to be tested.
