-4 Nitrous Pressure Gauge Kit

The NITROUS EXPRESS -4 Nitrous Pressure Gauge Kit is a mechanical analog pressure monitoring system designed specifically for nitrous oxide systems. This kit provides drivers with the ability to monitor system pressure in real-time, ensuring they can verify bottle charge status and injection cycles accurately. It is ideal for use in drag strips, road course competitions, and street performance vehicles.

Featuring a liquid-filled design, this gauge dampens needle fluctuations during rapid pressure changes, allowing for stable and readable pressure indications. The gauge is constructed to be reliable in high-vibration environments, eliminating the need for electronic components and simplifying troubleshooting. The white face of the gauge ensures high contrast readability under various lighting conditions.

Enthusiasts running direct-port or plate nitrous systems will find this gauge particularly beneficial for continuous pressure monitoring during tuning and competition. It allows drivers to set baseline pressure curves, verify bottle charge retention over multiple runs, and diagnose regulator performance with ease. The kit includes a 1/8-inch NPT connection and a -4 AN fitting for seamless integration into standard nitrous system feed lines.
