Review: Good Quality at a Great Price! - These are good quality pressure gauges. A lot of gauges at this price and higher are very cheap/cheesy, but these have a good quality feel to them. I use mine for water on my reverse osmosis system and they function really well and the price is great.
Review: this is what Pentair should have included - Appears to be a glass lens ( info I could not find before ordering ) and of good quality easy to read and looking forward to not having a yellow lens in a year

## Features

- This pressure gauge is built with brass and stainless steel parts to measure pressure in liquids and gases that aren't corrosive, like water, oil, and air pressure tests. It's perfect for use with things like air conditioning line repair, tanks, HVAC tools, air pumps, pipes, tube vacuum tests, and more.
- The round dial is safely tucked into a 304 stainless steel case to resist corrosion. Internal filling of glycerin in the pressure gauge ensures stable pointer readings and safeguards internal mechanisms against vibration damage.
- Red Range Mark: Easy sliding on the dial allows for effortless adjustment. The arrow-shaped design indicates the upper and lower limits, providing a quick and clear visual reference to remind you to stay within the safe pressure range.
- The dial adopts a dual scale for pressure measurement (-30 inHg-0/-1 bar-0). Its display accuracy conforms to ± 3/2/3% of the span (ASME B40.100 Grade B).
- The IP67 waterproof rating prevents condensation, eliminating window fogging and ensuring consistently clear readings.
- The connection is a lower mount male type with a 1/4" NPT thread, making it easy to set up in various systems.

### ⭐⭐⭐⭐⭐ Good Quality at a Great Price!
*by K***K on December 5, 2025*

These are good quality pressure gauges. A lot of gauges at this price and higher are very cheap/cheesy, but these have a good quality feel to them. I use mine for water on my reverse osmosis system and they function really well and the price is great.

### ⭐⭐⭐⭐⭐ this is what Pentair should have included
*by Z***N on February 19, 2026*

Appears to be a glass lens ( info I could not find before ordering ) and of good quality easy to read and looking forward to not having a yellow lens in a year

### ⭐⭐⭐⭐⭐ A well made guage that is ideal for my application.
*by S***E on July 4, 2024*

This 0-30 psi guage works perfectly for my application. A pressure guage needs to be sized for the expected pressure range. A guage is most accurate over the middle third of it's range (10-20 psi for this 0-30 psi guage) I use it on the discharge of a water pressure booster pump that supplies 20 psi when turned on and so this guage is ideal. The guage is well made and easy to read with two adjustable red sliders on the guage body which I use to denote the normal operating pressure range. It comes well packaged in bubble wrap and comes with clear instructions for "burping" the guage if it's not reading zero when it arrives. It also came with Teflon tape for a leak free installation. In the video you may notice that the installed guage is not reading zero when the pump is turned off and that's because I have an overhead water tank supplying about 3 psi of head pressure even when the pump is off which the gauge is reading correctly.
