Parker’s RWAH profile is the ultimate metal-clad excluder for heavy duty hydraulic applications. Press-fit installation prevents O.D. contamination while the additional sealing lip works in conjunction with Parker rod seals to provide redundant sealing for leakage reduction. An aggressive wiping lip, facing the environment, ensures the utmost performance in contaminant exclusion along the rod.
IMPORTANT: When using the RWAH wiper in conjunction with other rod seals, it is important to select a rod seal profile that enables pressure relief of fluid into the system, otherwise a pressure trap may form between the wiper and rod seal. Suggested rod profiles are the BT, BS, and B3 u-cups.
