North Star Proven Performance Northstar Pressure Washer Pressure Gauge - 5000 PSI, 3/8in. Fitting

funktioniert sehr gut

Setting the proper working pressure is key to setting up (or diagnosing) a pressure washer. I've found that the critical unloader valve is rarely set properly. Adjusting it ensures top performance and protects the pump. This gauge seems to work fine, though I didn't have a standard (calibration) gauge to compare it to. Movement is filled with mineral oil, and the damping worked fine in use. 5,000 PSI range is plenty for most portable pressure washers. Nice SS case, and good 3/8" quick disconnects I was able to diagnose a failing AR VMX 3G30D, and brought it back to life with new seals, valves, and unloader. The Valley Industries gauge then allowed unloader set up and performance check. I set the AR to ~2500 psi trigger pulled (3.5 orifice nozzle zero degrees ); 2850 psi trigger closed; with no pressure spike. This is about right for a 3000 psi pump. Make sure you use a new zero degree nozzle of correct orifice size when setting up yours, and don't allow trigger off pressure to exceed pump psi spec. Note that a good unloader is priceless (I used an AR 3 Gymatic) BTW, pressure is important, but its GPM that really makes a difference. Failing unloader or too high PSI setting will kill any pump in a hurry This gauge is a great tool - get one!

Used on gas pressure washer. Works perfect!!

Quite happy with this pressure gauge I use it every now and then worth every penny

I’ve only used it once so far, but it worked well and appears to be well-made. It’s great to finally stop guessing the PSI when pressure washing items with a maximum PSI limit, like my composite deck and composite outdoor furniture.
