Winters 2 inch Dial Size, Multi Function Economy Utility Dry Pressure Gauge, Brass Internals, Black Steel Case, Dual Scale 0-100 psi/kPa, 3-2-3% Accuracy, 1/4 inch NPT Bottom Mount, Pressure Gauge

Well made and works well .

When my first one arrived, it was showing 7 PSI out of the box. I did not even connect it. I contacted Amazon for a replacement. This is being used in an assembly that allows me to air up/down two tires at a time. We do off-roading and the ability to air up/down two tires at a time is a good thing. It also allows me to balance the pressure between the two tires. I also have the ability to check the line pressure with a regular tire gauge (just a back up). I have one electronic and two manual tire gauges that I use. All three of these read exactly the same at 40-65 PSI. The replacement gauge arrived two days later. It was at 0 PSI out of the box. I installed it and started checking...thinking a gauge at this price point would be way off. Actually what I found after testing it with my three tire gauges was impressive. At 40 PSI and below it reads about 1 PSI low. At 50-65 it reads exact to about 1/2 PSI high. I have used high-end, expensive, oil filled gauges that were no where this accurate. Bottom line...I am very pleased with the replacement and glad that I decided to stay with the same brand/seller, etc. Thanks!

I purchased three gauges to install on a water filtration system. After about a month, one failed. The failure was related to the needle "sticking" rather than a smooth movement during operation. I emailed the company directly, who informed me to go through Amazon for returns/rrplacement/warranty. I don't know what that says about the company, but I guess they don't want to deal with customers directly. Either way it's easy to install, the accuracy is about +/- 5% from what I can measure. The two working ones are smooth and easy to read. One part that I'm not too happy with is the two screws in the back are not stainless steel nor are they protected. So one of them somehow had water splashed in the and the screws are show rust after a month of usage. Didn't expect water tight Gauge, but also didn't expext rust from Gauge that is designed to measure water pressure as well.

For the money I expected leaks or incorrect readings. However, at a tenth the price of what my local plumbing supply house wanted for a guage, it was worth a shot. It’s been in a month so far, no leaks, reading makes sense, all I need.

If you use this were rain could encounter the gauge, ensure you mount this vertically to keep water from collecting inside the gauge. Had to replace the first one after a year when it stopped working. When i changed it, water came out of the opening to the gauge by the brass fitting connecting to the pipe. Rotated the pipe to keep the gauge vertically and hoping for a longer life.

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.

My day job is calibrating instrumentation at a nuclear power plant, so I have a tendency to over-analyze things that I use for home. Calibration out of the box was spot-on (tested on a Heise PTE-1 accurate to +/- 0.005%). I can't say that I would use these to prevent the next Fukushima, but for what I needed, they were superb. I installed these in my water filters so that I could see the static pressure at each stage during controlled flow, thus allowing me to see if any of the filters need to be changed without needing to open the canisters.

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.
