Review: Nice item - Good quality and works well
Review: Good Product - I have fluid in my tractor tires for extra ballast on my loader tractor. I bought this gauge to make a better tire pressure gauge for fluid in tires application. I have never found a good tire gauge that lasted more than a few months even though they were rated for fluid applications. This gauge works well and is accurate.

## Features

- Brass and Stainless Steel wetted parts for measuring non-corrosive liquid and gas pressure. Such as water, oil, and air pressure tests. Compatible with air conditioning line repair, tank, HVAC tools, air pump, pipe, tube vacuum test, etc.
- The circular dial is enclosed in a 304 stainless steel case for corrosion resistance. Glycerin filled inhibits pointer flutter and prevents damage to the internal mechanics from vibration and pulsation.
- Measures pressure with dual scale (-30 inHg-0-30 Psi/-100-200 kPa). Display accuracy is + or - 3/2/3% over the entire range of the gauge.
- IP67 waterproof prevents condensation inside causing fogging of the window. Offer clear reading.
- Lower mount male connection with 1/4" NPT thread.
