Pump Outlet Fitting

Metal fitting mounted on the pump outlet, connecting the valve block to the further high-pressure installation of the unit.

Application

The fitting carries pressurized water from the pump outlet to the rest of the installation – depending on the configuration, this may be a direct high-pressure hose connection or a link to another component in the system, such as a pressure gauge or regulating valve.

Symptoms – when to replace

• Water leak at the fitting's thread, despite a properly tightened connection on the other side.
• The thread is worn or damaged and the fitting nut cannot be tightened fully.
• Visible corrosion or cracking of the fitting body after prolonged use.
• Drop in working pressure, with no other visible cause at the pump outlet.

How to choose the right part

Selection is based on reference number 43077 – it's worth comparing with the removed fitting for thread and length, since Kränzle uses different outlet fitting variants depending on the model and installation configuration.

When replacing, check the condition of the seal (O-ring or washer) at the fitting's mounting point – a new fitting alone won't provide a tight seal if the seal itself is damaged.

FAQ

Does the system need to be drained of water before removing the fitting?|Yes, replacement requires depressurizing the high-pressure system – it's best to shut off the water supply and release pressure by opening the gun before starting disassembly.

I replaced the fitting but the leak persists – what else should I check?|Check the condition of the seal in the seat where the fitting screws in, and the tightness of the connection on the other side – the leak may come from the neighboring component rather than the fitting itself.
