Karcher Pressure Washer Piston Spring9.047-023.0

Genuine piston spring that goes between the piston and the cylinder wall. 

Prevents high-pressure water leak during the compression and power strokes of the pump. Helps absorb and dampen the shock, reduce vibrations. Stress is minimised on the pump components.

Piston springs create a barrier for combustion gas leaks. Also helps to reduce friction between the piston and cylinder wall so the piston moves smoothly within the pressure washer’s cylinder. Smoother operation and prolonged pump life for your pressure washer.
