Ceramic Plunger for 4014 / 4018 US Jetting Pumps

The ceramic plunger in the USJ high pressure water pump requires replacing only when cracked. Though there are 3 ceramic plungers per pump, it isn’t necessary to replace all three at once. Replace as needed and only when the plunger is cracked. Discoloration is normal, and does not mean the plunger should be replaced. Take caution with this part as it is very fragile.  This component is used only on 4000PSI at 14 and 18GPM US Jetting pumps.
