Description

How does a pipe union work on a Karcher pressure washer?

A pipe union on a Karcher pressure washer serves as a connection point between different sections of the water supply system. It’s made of two threaded fittings that can be joined or separated easily using a nut and a gasket. 

This allows for convenient assembly and disassembly of the pressure washer's water pipes, enabling maintenance, repairs, or customization of the water supply system.

When do you replace your pipe union?

Replace the pipe union if it becomes damaged, corroded, or develops leaks. Signs of a damaged pipe union include water seepage, a loose connection, or the inability to create a watertight seal. 

If the threads are stripped or the union is visibly cracked or degraded, replace it for a more secure and reliable connection in the water supply system. 

Is it a genuine spare part? 

This pipe union kit by Karcher is a genuine pressure washer replacement part. Your pressure washer can work good-as-new in cleaning surfaces.

Hi Ernest, I'm afraid we don't have this information. Please submit a part enquiry, including the TYP number, beginning 1., from the rating plate on the bottom of the pressure washer so we can check if this is compatible with your model.
