Product Overview

The CAT Pump Valve Kit 66DX (x3) is a genuine replacement kit designed to maintain the performance and reliability of your CAT plunger pump. Over time, pump valves can wear, causing reduced efficiency, pressure loss, or pulsation. Replacing them with an OEM valve kit ensures your pump continues to operate at peak performance with maximum flow and pressure consistency.

This kit includes three valve assemblies, manufactured to CAT Pump’s high standards for durability and precision.
