2-1/16in DG/B Nitrous Pressure Gauge

The AutoMeter 2-1/16in DG/B Nitrous Pressure Gauge is a precision diagnostic instrument essential for any serious nitrous oxide system operator or high-performance engine builder. This gauge monitors nitrous bottle pressure in real-time, ensuring your system maintains optimal operating conditions and preventing dangerous over-pressurization that could damage fuel injectors, regulators, or engine components.

Featuring a direct glycerin-filled design (DG/B designation), this gauge dampens needle oscillation caused by vibration and system pulsing, delivering stable, readable pressure data even under aggressive throttle application. The gauge's dual-range face indicates both pressure and performance margin, allowing you to confirm bottle integrity before each run and catch slow leaks that could compromise boost delivery mid-race.

Nitrous system operators benefit most from this gauge during initial setup validation, seasonal bottle recertification checks, and in-vehicle diagnostics when response feels sluggish or inconsistent. Its compact design accommodates tight dashboard or A-pillar pod installations without consuming excessive space, while the lightweight construction is critical for weight-conscious competition vehicles.
