Measureman 2-1/2" Dial Size, Glycerin Filled Pressure Gauge, 0-100psi/kpa, 304 Stainless Steel Case, 1/4" NPT Lower Mount

Nice gauges..I use 2 to measure fuel and air pressures on my Optimax outboard.

Funciona perfectamente.

I recently purchased this glycerin-filled pressure gauge, and I am thoroughly impressed with its performance and quality. The gauge provides accurate and stable readings even in fluctuating conditions. The glycerin filling minimizes needle vibration, which is particularly useful in high-vibration environments, ensuring precise monitoring without the distracting jitter. Additionally, the build quality feels robust and durable, suggesting long-term reliability. To top it off, the clear display is easy to read, even at a glance. Overall, this pressure gauge is a reliable tool that meets professional standards and enhances measurement accuracy of our pool equipment.

Nice gauge for my poor man's irrigation system - had to buy a reducer to attach this to my lake pump but it fit like a glove with no leaks - love brass fittings. I need to check the pressure at the pump once in a while. The gauge seems to be very accurate -- but as long as it's plus or minus 10%, I'm a happy camper. I would buy this again.

Gauge quality is quite good, however the oil level is low making it difficult to read the very top part of the dial. Should have only a very small air pocket at top. This one needed another half an once.
