## Customer Reviews

### ⭐⭐⭐⭐⭐ Just what I expected
*by J***N on February 25, 2025*

This is pricey but it's the exact match

### ⭐⭐⭐⭐⭐ Excellent Product!
*by W***D on August 3, 2024*

Hard to find fluid additive but exactly what the gauge required!

### ⭐⭐⭐⭐⭐ Easy to use
*by D***K on March 25, 2021*

This gage fluid is widely used in Dwyer pressure gauges used for radon mitigation systems. Over a period of years, the level goes down and it needs to be refilled. You can do it yourself! Just disconnect the tubing, add this fluid through the fill port, and adjust the knob to set the zero level. Then reconnect the tubing and you're done. The main mistake you can make is to add too much, in which case you'll need to fish a piece of paper towel (or pipe cleaner) down into the fill hole to remove some excess. I made that mistake, but even so, the whole process was 10 minutes.
