-4 Nitrous Pressure Gauge Kit

The NITROUS EXPRESS -4 Nitrous Pressure Gauge Kit is a mechanical analog pressure monitoring system purpose-built for nitrous oxide systems. This 0-1500 psi gauge delivers real-time feedback on system pressure, enabling drivers to verify bottle charge status and monitor injection cycles with precision. The liquid-filled design dampens needle fluctuation under rapid pressure changes, ensuring stable, readable pressure indication during active nitrous deployment on drag strips, road course competition, and street performance vehicles.

Specified with a 1.5-inch diameter gauge face and full-sweep needle movement, this kit accommodates direct visibility in tight engine bay installations. The white face delivers high contrast readability under varied lighting conditions. Port configuration includes a 1/8-inch NPT connection for system plumbing and an -4 AN fitting for integration into standard nitrous system feed lines. The mechanical design eliminates electronic dependence, making it reliable in high-vibration environments and simplifying troubleshooting when system diagnostics are needed.

This gauge is suited for enthusiasts running direct-port or plate nitrous systems who require continuous pressure monitoring during tuning and competition. Drivers setting baseline pressure curves, verifying bottle charge retention over multiple runs, or diagnosing regulator performance benefit from the instantaneous analog readout. The -4 AN fitting accommodates adapters for integration into existing nitrous distribution manifolds and solenoid valve assemblies without requiring system redesign.

NITROUS EXPRESS is recognized for precision nitrous system components engineered to OEM-level tolerances. The -4 Nitrous Pressure Gauge Kit meets the specification standards required for consistent, repeatable performance monitoring across sequential injection cycles and multi-stage nitrous applications on naturally aspirated and boosted platforms.
