Installation doesn’t get much easier with our brand-new Liquid Filled Series Mechanical 1-1/2” (38mm) Nitrous Pressure Gauges.

There are two versions in stock so you can go with either a Black Dial Analog with White Needle or White Dial Analog with Black Needle Gauge depending on which version you like best for your car or truck.

This is a simple gauge with a clean look and it’s easy to use. There’s no wiring or hardware involved and all you have to do is attach it directly to your vehicle’s nitrous tank with the 1/8-27 NPT Male Thread on the back. View readings from 0 to 1500 PSI and know exactly where your tank’s pressure level is.

The liquid-filled feature ensures that our nitrous bottle pressure gauges deliver precise readouts. Each gauge is filled with silicone oil which protects the needle from shaking and engine vibrations which can affect readings. You’re getting a tough nitrous oxide pressure gauge that’s housed in a waterproof chrome body with a trim ring so it’s built to be durable.

We moved forward with developing this NOS nitrous pressure gauge after seeing the strong response to the fuel pressure gauges in our Liquid Filled Gauge Series. We also want to expand on this lineup overall because it combines simplicity and reliability with a great looking design.
