2-1/2" Liquid Filled Pressure Gauges - Stainless Steel Case, Brass, 1/4" NPT, Center Back Mount Connection, 0-15PSI

I bought this to replace the broken gauge in my Jandy CL pool filter. The replacement Jandy unit is plastic and cheap and costs over $30. This gauge is all metal, oil filled, and seems to be much better quality.I thought my filters were hanging in there because my broken gauge was stuck at 12 psi. For how long I'm not sure. After installing this I realized I may need to buy new pool filters. A broken pressure gauge concealing bad filters can lead to broken pool pumps, exploding filter housings, and o rings.One thing to consider is that I had to grind off about a 1/2" of the plastic outer gauge housing on the Jandy to get this new gauge to screw all the way in. It took 30 seconds with a grinder. If you don't want to to do this you can buy an adapter like this: https://www.amazon.com/Dixon-D344R-Fitting-Swivel-Pressure/dp/B00835RQBU/ref=sr_1_28?crid=3VVHKSL60EF8T&keywords=1%2F4+npt+male+to+1%2F4+npt+female&qid=1561590419&s=industrial&sprefix=1%2F4%22+npt+male+to+1%2F4%22+npt+female%2Cindustrial%2C152&sr=1-28With this you'll be all set.

I bought this gauge to replace the tiny one what came with my airbrush pressure regulator. Strictly speaking, it's a bit big for this application - however, it's much easier for me to read from a normal working distance. The liquid filling does keep the needle from bouncing when the air compressor runs; apart from that, I don't have much use for it. Overall, this seems to be a high-quality piece of kit and I'm glad I bought it.

Permanently installed for my household water pressure and working great. I have mine mounted in my garage near the hot water heater. I learned the hard way that it is important to monitor city water pressure when you have a pressure reducing valve installed. My water pressure shot up to 140 psi and pretty much ruined my old water heater over time. I suspect the pressure has been this way for the past 5 years which is when we bought the house. The PRV is supposed to regulate the pressure but mine was shot. Now, I not only have a new PRV and hot water heater but I added a much needed expansion tank as well. I have my PRV adjusted for 70 psi and the system is working great. And I know that because of this wonderful pressure gauge! You can buy the temp units at the big box store (or here) but I like seeing mine everyday. The fluid filled gauge should bring years of reliability.

Works greatUsing it with my freeze dryer unit to monitor vacuum.Oil filles is always the best way to go.Do not need a calibrated gage or an expensive electronic gageThere was an issue with my gage and I need to say even though it was partly my fault they replaced the gage.A note to other customers if the gage has a small brass plug and you need to pull this to zero the gage (pressure differential) do not remove the small brass plug just pull it up a little and when you press it back be careful not to push the black elastomer plug too hard or it can pop into the gage.TOP QUALITY CUSTOMER service really stands out here above everything.

I’m not impressed. This is not the first oil filled gauge I’ve owned but it’s the first to leak oil all over before being installed. We’ll see if it even works. If it is just an orientation thing and otherwise works it may still be a good value for the money. I’ll probably check it against another higher quality gauge to check accuracy.

Looks to be a fine instrument .. gonna buy 3 more of the the normal "stand-up" vertically installed configuration, to change out from the common "building supply" offerings currently in service. The oil dampens pump pulses, and a heck of a lot easier to read more accurately. Two will go to measure the pressure differential across a 20 micron whole-house sediment input filter cartridge.

This gauge appears to be of very good quality. It feels nice and solid, and says it is made in the US. It's ideal for replacing your pool filter's gauge, which typically are not anywhere near as good as this one. I did not cut off the rubber nipple or pierce it for fear that the glycerin inside would leak out, and or moisture would find a way in. In my case it calibrated spot on, and just not needed.

This is for the 2 1/2" liquid filled gauge, center back mount 0-100 PSI. Got 4 of these for my filtration system on my well. I put a gauge on both sides of each filter so I can tell when there is a pressure drop on the downstream of the filter. That will help me to know when to change the filter. The gauges are very sturdy and quality made. Dial is easy to read. Shipped fast. Very happy.
