Want to know exactly what pressure your pressure washer is putting out? This solid metal gauge screws right into your machine's outlet (it has an M14 x 1.5 thread, which is common on many models). It has a clear dial that reads from 0 all the way up to 250 Bar (that's about 3500 PSI), so you can monitor your pressure in real-time. This is super helpful for adjusting the nozzle or settings to get the perfect clean without damaging delicate surfaces. It's made from alloy and stainless steel, built to handle the high pressure and vibration. Suitable for machines rated up to about 5.5KW. Installing it is usually straightforward – just make sure your machine is off and depressurized first. A simple, affordable upgrade that gives you more control and helps with troubleshooting if your washer seems underpowered. A must-have for serious cleaning jobs.
