Pressure gauge 0-250 bar 1/8" Junior

The pressure gauge for Kränzle Junior 1/8" Ø40 mm is a measuring component designed to monitor operating pressure in a pressure washer. In service practice, it is used to assess system operation, helps diagnose pressure drops, and allows ongoing observation of the machine’s operating stability.

MPN / reference: 43051
Connection: 1/8"
Dial diameter: Ø40 mm

APPLICATION

The pressure gauge is used in typical operating and service work:

• monitoring operating pressure in Kränzle Junior washers,
• diagnosing pressure drops and unstable system operation,
• replacement of a damaged or unreadable indicator,
• checking parameters after pump or accessory repair,
• inspection of machines used regularly for cleaning work.

SYMPTOMS - WHEN IT IS WORTH REPLACING

It is worth considering replacement of the pressure gauge when the following appear:

• no proper pressure indication,
• the pointer stops, vibrates, or reacts with delay,
• the scale is unreadable or the lens is damaged,
• leak in the area of the pressure gauge connection,
• difficulty assessing the actual operating parameters of the machine.

HOW TO CHOOSE THE RIGHT PART

Selection of the pressure gauge should be unambiguous:

• confirm that it is intended for Kränzle Junior,
• verify the 1/8" connection,
• check the Ø40 mm diameter,
• confirm the manufacturer number: MPN 43051,
• compare the mounting method with the removed part.

For measuring components, not only the thread matters, but also the housing diameter and fit to the mounting location.

COMPATIBILITY

The pressure gauge should be selected based on MPN 43051, the 1/8" connection, and the Ø40 mm diameter, according to the machine’s service documentation or by comparison with the removed part. The part should not be selected solely by the general description “pressure gauge for a washer.”

[faq]

Does the smaller Ø40 mm diameter matter, or is it only about mounting appearance?|It matters in practice. The diameter affects fit to the mounting location and whether the pressure gauge will fit and remain readable in the specific machine housing or panel.

Can a pressure gauge for the Junior model be chosen only by the 1/8" thread?|No. The thread is very important, but you still need to confirm the housing diameter, mounting method, and compatibility by MPN 43051.

What can it mean if the pressure gauge shows pressure, but the washer clearly works more weakly?|It may indicate a problem with the reading itself or with another part of the system, such as the nozzle, valves, pump, or a leak. The pressure gauge is helpful, but diagnosis should also be based on the machine’s behavior.

Is it worth replacing the pressure gauge if only the lens is cracked, but the readings seem correct?|Yes, especially if the damage makes reading difficult or increases the risk of further damage to the mechanism. In service work, indicator readability matters a lot.

How can I check after installation whether the new pressure gauge works properly?|After installation, it is worth checking connection tightness, observing smooth pointer movement, and comparing the reading with the actual behavior of the washer during operation under load.
