Description

The AR (Annovi Reverberi) Kit 42467 is the complete ceramic plunger (piston) replacement set for the RC and RCA series pumps. These series are common on professional-grade pressure washers, and because they often run at high pressures ($2,500$ to $3,000$ PSI), the ceramic sleeves can eventually wear down, crack, or “frost.”

This kit provides the 18mm ceramic components and the necessary internal seals to ensure the plunger rod remains watertight and oil-tight.
