The CAT Pumps 33060BE Valve Kit is a genuine replacement valve repair set for CAT Pumps 5CP3120 and 5CP5120 plunger pumps. The kit uses standard NBR seals and comprises the core valve components—O-rings and seats, valves, springs, a retainer, valve plugs, and backup rings—necessary to rebuild the pump’s valve assemblies. Silicone oil or grease is recommended during installation to ensure proper seating and performance.
