Stainless Steel Pressure Gauge Dual Display (0-5000 psi/kPa) - 2 1-2" Glycerine Liquid Filled Water Air Oil Gas Gauge with Polycarbonate Lens & Brass Connection -1/4" NPT Lower Mount

The gauge is sturdy and clear. The gauge fit well and is easy to read. I have to guess the gauge is accurate because I have not had time to calibrate it. So far so good. I’m using the gauge alongside a 4000 pound gauge on a large Nitrogen tank in my shop for filling tires on my rubber tire Backhoe, Skid Loader, Dump Truck tires and heavy equipment trailers. I also use this tank And gauges as a backup for my smaller tanks I use for HVAC work to pressurize and purge condensing units when my smaller tanks run out to keep me from driving 60+ miles round trip to the local supply house to swap tanks.Pros: the gauge is sturdy and hasn’t given me any problems yet.Cons: the seal on the gauges have a rubber stopper used I assume to fill the gauges with their Glycerin fluid and it doesn’t take much contact when with any of the hundreds of tools riding around in the back of the service van that always seem to fall out of there compartments when hard braking because of distract drivers or wildlife in the road that cause a hard breaking situation.I tell you this because I have hat to replace the previous one I have that started leaking shortly after installing it. I can’t be certain that it was an object or handling that caused the gauge to leak but I noticed the gauge leaking shortly after installation and the seal was the only thing that was not seated properly to keep it from leaking. I saw no other damage to the gauge but I wasn’t going to blame the seller because of the environment the tank was in where any number of a hundred things could have occurred to damage the seal and I did not inspect it after installing it. The cost is not so expensive that it’s worth the time of returning it or being dishonest and trying to made up some kind of excuse for why the seal failed, besides I wouldn’t do that any way because it’s not a Godly or honorable thing to do. I’ve been in business for over 30 years and I see to much dishonesty and fraud in our society.Conclusion: the gauges are worth the money and I’d buy them again if I damage them by mishandling or an accident caused by not securing the tanks and protecting them properly when transporting. They are a good buy.

I use many gauges of various quality and cost. For the price, these are great. I calibrated several of them against a high-precision gauge and they were spot on. I have bought over 20 of these and they all work great.

Great purchase. Value for money, good quality and fast delivery. Would definitely recommend.

This is a beautiful gauge. Highly polished and the plated connector adds to its quality "feel". I have this to measure pressure on a water tank. The tank is on a hill and when full reads about 11 psi. It measures pressure at the pump inlet so gets a surge every time the pump kicks on. That is why I need a liquid filled gauge. My last gauge lasted a few years but finally wore out, reading lower and lower as time went on. This gauge read pressure fine and is working perfectly. Time will tell how durable it is. Made in China and not NSF since it does not use lead free brass, but I am not a prune picker (Californian) so don't care about an insignificant trace of lead.

Received product as was stated.I have installed and replaced alot of pressure gauges in well systems.This gauge is the best overallm so far and I will be purchasing more to replace all my clients gauges in all the well houses.Apart from being liquid filled it has a open/close lever on the top plug so you do not need to pull the plug after install or snip the niplle off.Being stainless steel with a brass chrome plated thread is a plus along with a 2 1/2 in dia.I only need a 0 to 100 psi gauge so numbeers and indentations are large and clear.You can not beat the price.I called the company ang got to speak to someone,that is a plus,made in America.It works as it should ,I am very happy.I carry a bottle of 99.7 % "CLEAR" glycerine with me for top ups if I find the liquid level a bit low,I like to have the indicator lever tip in the liquid at all pressure readings as I use the gauges in the 40 to 60 psi range .

Easy to install and validated pump pressure

I didn’t like that it doesn’t work at all and I could hear bubbling inside it while the gauge never moved but I only pressurized it with a hand pump to 25-30 psi and the thing blew up and the needle on the gauge never moved in the slightest bit. I suspect it had an internal leak as glycerin also leaked into my system but it’s a giant POS and not worth the effort to even install it never mind throw it out when it proves useless as it will.

Great product! Great price!
