Part Number: 8.751-237.0-KAR
OEM / Old Part Number(s): 87512370

This 18 mm Karcher Ceramic Plunger Sleeve Kit includes ONE (1) each of the following: 18mm ceramic piston sleeve, plunger bolt, o-ring and copper spacer. Please purchase three (3) kits to replace all ceramic pistons in a pump.

Cracked or broken ceramic piston sleeves can cause further pump damage if not repaired immediately. Some pump damage can be so extensive as to require replacement of the entire pump. Identification of broken or cracked ceramic plunger sleeves can be difficult, however one sign to look for is milky or caramel colored pump oil, which indicates water has entered the pump body and mixed with the pump oil.

For use in Karcher Pump Models: KM4035.2, KM4035.3, KM6035.2, KM6035.3
