MEASUREMAN 2" Forged Brass Gas Pressure Test Gauge Assembly, 3/4" FNPT Connection, 0-30psi, +/-3-2-3% Accuracy

I tested my new natural gas piping job and had a substantial leak. Turned out it was this gauge leaking in 2 places: 1) Where the gauge screwed into the brass body 2) The Schrader bicycle valve. After teflon taping the first, and tightening the second, the gauge seems to be working fine. Hard for me to understand that a tool meant to test pressure is itself the cause of the leak ... poor quality control.

We installed a new gas line and needed to pressure test it before closing the walls.I needed a 3/4 to 1/2" brass pipe adaptor to attach to the system.Also best using a cordless tire inflator. Set the target pressure and let it alone. We left it over night, no leaks. Local code requires 15psi for 30 minutes. Some codes also stipulate the test pressure be 50% of the range of the gauge. You can swap out the gauge or buy 2 of these and change a gauge, or buy another with a different range.Happy with my purchase. Not sure how impact resistant thr gauge is so don't toss it in your tool box. Mine lives in a case protected from the dangers of day to day work.

Small word to the wise. Make sure you verify the Schrader valve is sealing. It took a couple of minutes to realize that my leak was in the valve, not my propane system. Tighten with a valve stem tool.

We ran gas pipe and connected the test gauge. I put 8 psi of pressure on the pipes. The next day the gauge read zero psi. We looked for leaks with soapy water and couldn't find anything. So, we took out all the pipe and reinstalled them....connected the gauge and again, the next day it was at zero.I finally took one section of pipe and capped one end and put the gauge on the other. The next day it was at zero again. I don't know if the gauge is bad or what. We cannot find a leak but the system does not hold air.

I really want to like this gauge - the all-brass construction is great, range is perfect for testing DWV, natural gas, and pool plumbing lines, and the schraeder is of good-quality construction.However, the gauge leaked at first use, at the inlet of the reducer (3/4" FPT). I use a 3/4" iron nipple, w/ teflon tape and it leaked ~1psi an hour. I removed the nipple and reinstalled w/ teflon paste, and it continued to leak. I inspected the fitting and cannot see any discernible damage. I tightened it beyond the realm of what I'd ever expect to tighten an NPT fitting, and it continued to leak at this joint.

If you do your own plumbing around your home, checking for leaks with soapy water is not enough. To insure your safety, buy a kit like this to pressure-test your work for a good length of time, say, hours-to-days. Never get in a hurry to finish the job and skip this test, Once you open the box it comes in, make sure the Schrader valve is tight in the housing and use pipe dope to any connections you make to this tester. The valve only goes to 30 PSI on this one, so take that into consideration to make sure that's going to handle whatever pressure you are going to test with. Very well made little tool.

Used to air test a new whole-house PEX installation for leaks before water testing. Worked great. Used a 3/4” NPT male PEX fitting to join to the system. Wrapped the fitting with the included Teflon tape and had no air leaks. Schrader valve was tight to gauge body; threads looked to be factory sealed with some type of translucent permanent thread sealant. Cap for Schrader valve is included.I would say the gauge is accurate, in that the reading on this gauge and the gauge at the pressure reducer on the system read exactly the same throughout the test. Put 80psi on the system and it held for a week without change. For the price and quality, I’d definitely recommend it.

It works as described. Recently ran new underground and new interior gas lines and this has been important to test for leakage. Ive put it under pressure for 24hrs several times and it’s still functioning.Minus 1 star because the pipe wrench slight tapped the clear plastic knocking it out. Was able to pop it back in.

Needed to pressure test a system, had a very slow leak, and considered the possibility of the Guage as being the leak... so I capped it and ran a test for 24h, it didn't leak at all. So the gauge is excellent. I later found the culprit of my slow leak, which once resolved was then verified after another 24h.

The dial itself seems to work pretty accurately, the problem comes in when trying to hold pressure in. At 6 pounds, it wouldn't hold pressure, wasted a bunch of time soap testing every joint inside looking for the leak, at 30 pounds same thing, found the leak to be right at the fitting on the dial where you hook up your compressor to, that 1/8 threaded connection thing. Had a decent crack in it, Teflon taped and doped it up trying to seal it. Just a huge waste of time, might try to find new fittings and reuse the dial on a different assembly, we'll see! I do not recommend this product

Never worked, looked closer and it looked like the gauge was screwed with epoxy to ensure it doesn’t leak at the threads but they put to much glue and they glued over the valve entry whole. This rendered the product useless and could not fix it.Never the less amazon did right by me and made it right. Thanks amazon.

The valve to pump it leaks! 100% useless! After pumping it up with the large end properly sealed and screwing the cap on, then putting it under water, air bubbles were seen coming from the part that you attach the air pump to and nowhere else. The pressure will eventually leak out entirely over time.

It threaded easily into the 3/4 inch black pipe, so easy install, and correct threading..Works well..
