ERSATZTEILSATZ PRESSURE COMPENSATOR, .X-DESIGN, 066-250 VITON

Correct, this Ersatzteilsatz Pressure Compensator kit includes the Viton seals needed for maintenance and rebuild of the pressure compensator on your Hydrokraft X-Design piston pump, size 066-250. It does not include the entire pressure compensator assembly.

For Hydrokraft piston pumps using the X-Design pressure compensator in the 066 through 250 size range, this is the intended replacement kit for pressure compensator service and rebuild work, supplied as a direct service replacement component.

For X-Design units in that size range, yes, this is the correct rebuild kit. It covers the full 066-250 series and is sold as a direct service replacement for the pressure compensator assembly. The kit comes with Viton seals, so if your system runs at elevated temps or uses a fluid that can be hard on standard elastomers, that's already accounted for. Just confirm your unit falls under the X-Design designation before ordering.
