Description
What does the pressure piston do for the pressure washer?
The pressure piston works by reciprocating back and forth inside the cylinder, creating pressure that forces water through the nozzle. As the piston moves, it compresses the water and increases its pressure, allowing for powerful and efficient cleaning performance.
What causes the manifold and pressure piston to fail?
One common cause is wear and tear due to regular usage over time. The constant high-pressure operation can lead to the degradation of seals, O-rings, and other internal components, eventually resulting in leaks or loss of pressure. Exposure to harsh chemicals, inadequate lubrication, or improper maintenance can also contribute to premature failure.
Additionally, the presence of debris, dirt, or contaminants in the water supply can cause damage to the manifold and pressure piston. These particles can clog or damage the internal components, affecting their proper functioning and leading to performance issues or failure.
Is it a genuine spare part?
This manifold and pressure piston by Karcher is a genuine pressure washer replacement part. Your pressure washer can work good-as-new in cleaning surfaces.

Latest Product Review(s)
Really worth buying
my K4 pressure washer was leaking badly from under the metal housing at the top of the pump. This was a hairline split in the plastic manifold. The change is tricky but only needs basic tools. Recommend replacing the O-rings at the same time. If you don't want to dismantle the pressure pump with the sprung pistons, then hold them down with cable ties before undoing the metal housing. You will have to retrieve some internal parts from the old manifold to instal in the new one. Take an hour or so, but so much better and cheaper than throwing away a perfectly good pressure washer. Ransom Spares have all the necessary parts for a complete overhaul of the pressure washer. Buy the O-ring seal kit set, the triangular form seal, metal fork and O-ring seal gasket at the same time.
Karcher k4 Pressure loss.
I replaced this part to try and restore the pressure of my K4. This along with the cylinder head did the job.
Easy to fit
I purchased this part and was expecting a full assembly, it comes with the pressure piston, but not the one way valve and centre piston. Product was easy to fit and was a quality part.
Both K4 pressure washers up and Running
