CARBO Instruments Stainless Steel Pressure Gauge Dual Display (0-4000 psi/kPa) - 2 1-2" Glycerine Liquid Filled Water Air Oil Gas Gauge with Polycarbonate Lens & Brass Connection- 1/4" NPT Lower Mount

very high quality gauge - l mounted them outside of my shop for compressors - look nice - clean now - let you know in 6 mos. how they held up being close to the beach and covered by the carport - l put a coat of good wax on them before mounting - they should be fine

Works and I’ve had no issues with it

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.

Like the gauge. markings are a bit difficult to see.

Great price for an even better gauge. This one comes with dial markers for low and high attached to the ring face and one of the lowest prices.

My Carbo gauge looks like a very good purchase. now with this new gauge, i have no doubt that i am getting an accurate measurement. the liquid filled gauge is very easy to read. It looks well constructed and should last a long time.

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 .

The gauge stoped working after 20 mins of use, In the middle of pressure washing with an 8k pressure washer unit while on the trigger it’s reading 0 PSI

exactly what I needed

It was very good

I tested it with the arb gauge as well as the petrol pump gauge and it shows the same reading. Very accurate. Will post an update a after a few months.
