This 20 mm Hotsy Ceramic Plunger Sleeve Kit includes ONE (1) each of the following: 20mm ceramic piston sleeve, plunger bolt, o-ring and copper spacer. Please purchase three (3) kits to replace all ceramic pistons in a Hotsy pump.

Ceramic piston (plunger) sleeves can sometimes break or crack and require replacement before causing further damage within the pump head. Running a power washer in bypass for long periods then suddenly pulling the trigger gun can cause the new supply of cold water to crack the ceramic pistons, which had received excessive heat while in bypass. If not replaced immediately, these broken ceramic plungers can score the brass of the seal housing, pump heads, as well as being flushed through the system causing damage to the unloader and other components.

For use with Hotsy Pump Models: H450, HC600, HC930R
