Winters 2-1/2" Dial Size, Liquid Filled Industrial Pressure Gauge, Brass Internals, 304 Stainless Steel Case, Dual Scale 0-100 psi/kPa, 1.5% Acc, 1/4" NPT Back Mount, Glycerin Filled Pressure Gauge

These work well and are easy to install. Purchased to replace a couple of air compressor gauges that stopped working or filled with condensation. Needles jump all around in the stock gauges on gas driven air compressors. So Now when replacing gauges I look for glycerin filled over and others. Needle does not take a beating and the glycerin counter acts the condensation and extends the life of the gauge. Large 2 inch face is much easier to see from a distance than small stock gauges as well. Get your self some Teflon tape and you'll be up and running in minutes. These have been in service for about 22 months now on wheel barrow type compressors and the take what the guys can dish out on daily use compressors with no failures or issues to date, 10/10/2018. Update 08/31/20 Gauge holds up well, except when tools are dropped on them. We switched to these gauges after trying cheaper glycerin filled, which failed, and seal permitted glycerin to exit back of gauge and enter air tank and into the air system. Thanks Winter's and Amazon.

Used on a big mobile compressor. Previous gauge was a nightmare to read due to bouncing-finally failed. The gauge is rock solid while running and very easy to read.

This gage was purchased for use on the swimming pool filter as a replacement for the cheap plastic lensed gage which became unreadable from fogging up. This gage is insulated from vibration damage by being oil filled and has a glass lens, so it will remain readable for decades. It was noted that if the oil ever leaks from the gage and the air bubble at the top grows, a port on the rubber seal on top of the gage will allow you to top off the gage with mineral oil.

Needed to replace this gauge for my truckmount carpet cleaner, Not only was it IDENTICAL to the factory (less PROCHEM branding) it was accurate ! Cost was a 10th of the price of the "factory" replacement ! Very satisfied !!

Works great. I used it on my pool filer, didn’t need to be fluid filled but I thought this might have a longer life. Been about a year and a half, goin strong no prob!

Exactly what it was supposed to be. Works properly. In hindsight, after installing, would have preferred that I purchased larger dial size, but this is an excellent small dial that would be good for things like small compressors or tight spaces. As with all liquid filled gauges, needle doesn't jump or vibrate. Stainless steel is rust resistant, good quality.

I have Winters liquid filled gauges on most of my pneumatics. Quality gauge that is at a reasonable price point. Packaged well. Quick shipping.

This seems to be a very high quality gauge, but I don’t have a known good reference to compare it to, so I can’t vouch for its accuracy. It is very solidly built with a stainless steel housing and what appears to be a glass face, definitely not the cheap junk you see so often these days. It is also very easy to read, with large numbers and reference marks on the face.
