0-3 Psi Low Pressure Gauge, Capsule Gauge, 2-1/2" Dial Size, 1/4" NPT Lower Mount, Zero Adjustment, for Air Water Gas Pressure Test

I added this gauge to the propane supply of my on demand hot water heater that was not working correctly. Water was too cold from time to time. Reviewing the input requirements for the heater, the pressure was at the minimum required. I then went to the propane tank pressure regulator, removed the cap and and raised the pressure by turning the pressure adjustment clockwise with a screw driver. The pressure on the gauge now reads 11 to 14 inches which the heater requires. The reading remains stable in that range during use. An inexpensive fix for what I thought might be a major expense.

Works great

This item works great. Amazon also sold the attachments that allowed this pressure gauge to work on a tire nipple.

Received as advertised. Good initial quality. Accurate readings. The only issue with this gauge is the plastic lense can be taken off with ease, came off quite a few times during install, I’m sure it will stay in place now that is has been installed. Only reason it received 4 stars…..

I used this to test the Water Column (W.C.) pressure coming into my house at the pressure regulator, sourced from a large underground propane tank. I needed to confirm that the range top, water heaters and fireplace were all receiving the specified 13 W.C. pressure.Closed the shutoff valve on the main line going into the regulator, unscrewed the cap on top, screwed in the gauge, slowly opened the shutoff valve and the gauge nicely diaplayed the incoming pressure.I made a small adjustment on the regulator, then closed the shutoff valve, removed the gauge, replaced the cap screw and reopened the shutoff valve.Saved a $150 service call.

Works perfectly. Used to make my own bagpipe gauge. Will be ordering more.

Hopefully this will last longer than my last pressure gauge from another manufacturer that only lasted about a year outside on my babeque. This is more solid, is plated & the price is about the same. I use it in conjunction with a small valve to dial in the flame on my barbeque side burner to roast green coffee beans. Controlling the temperature is an important factor in that process & the gauge is perfect to monitor the flame from the propane gas burner. It took a lot of expirmentation to find the right flame levels but now I just turn the flame down by the numbers & can replicate decent rosting profiles with some consistancy.

It works great and the quality / materials of construction looks good.
