Does the job!

Accurate & easy to install

Read this before you buy this gauge. Just a few things I noticed after buying and installing 5 of these gauges. On a side note: I purchased 2 gauges from home depot and the both stopped working, stuck needle and bent needle after a few weeks and one rusted and sprung a leak.Likes:-much better quality then the cheap similar priced ones at lowes or home depot.-quality brass internal parts-screws instead of rivets holding the face on-Accurate: out of 5 gauges only 1 reads 1PSI higher then the rest. However they read 5 PSI different then the CHEAPO gauges from Depot and Lowes.dislikes:-the face is hard to read and only calls out every 20 PSI which is not ideal. Mine are installed on a house water system that reach 60psi max so its hard to tell from a quick glance if your at 50psi or not.-KPA is just distracting and not necessary on a small gauge like this in my opinion.

Replacement gauge in a professional setting, these can be sent out for cal, and for this price better than some on McMaster or granger.

To check for the best time to clean your swimming pool filter one needs a accurate preassure guage.I replaced my 10 year old preassure gauge and instatly found out I was getiing wronge readings. The old guage was showing low preassure. I changed this easily and I preciesly know when to clean the filter. The preassure reading keeps going up as the filter keeps getting dirty. A must have change in your pool filter if your guage is more than 2 years old.

Installed these gauges on both of my filters. A gauge gives you a better idea of filter condition as opposed to filter appearance. Easy to add the gauge. I just drill a 7/16" hole in the output side of the housing and thread it with a 1/4" pipe tap. Put a few wraps of Teflon tape on the gauge threads and thread it in.

Worked great to set pressure of torpedo heater after a tune up.

Very good gauge, going on my 3rd because I can get careless at work and drop or over pressurize. But, for your hard working dollar it's worth it if you take care of it. I use mine from shop air, to a 90 degree valve, to a pressure regulator, then the Winters gauge, to an air chuck. I use this gauge to pressurized and monitor coolant systems on diesel transit coaches. I use this to apply only 16psi or 11psi depending on engine, to find coolant leaks, and to verify repairs. Apply the specified pressure, cut off shop air, monitor gauge, hopefully the needle holds after repairs. Easy peasy. When I break the next one, I'll just buy 2 at a time. Just wish they offered a rubber boot of some sort.
