2 5/8in Ultralite

The AutoMeter 2 5/8in Ultralite nitrous pressure gauge is a purpose-built instrument for high-performance and racing applications where real-time nitrous oxide system monitoring is critical. Designed for drivers and technicians who demand accuracy under extreme conditions, this mechanical analog gauge delivers reliable pressure readings from 0–2000 psi without electronic dependency. Whether you're running a street-legal supercharger setup or a dedicated drag racing platform, this compact gauge integrates seamlessly into modern and classic dash configurations alike.

Built with AutoMeter's proven Ultralite construction, this 2 5/8-inch diameter gauge minimizes weight (0.72 lbs) while maintaining mechanical precision through full-sweep analog needle response. The silver face with black lettering delivers high contrast visibility even under varying lighting conditions typical in performance vehicle cockpits. Fully mechanical operation eliminates wiring complexity and potential electrical failure points—a critical advantage when nitrogen oxide pressure stability directly impacts combustion control and engine safety. The gauge's compact footprint (5.65 x 5.6 x 5.7 inches) allows flexible mounting on custom dash panels, steering column pods, or A-pillar installations without consuming valuable interior real estate.

This gauge is essential for nitrous system operators who require constant bottle pressure verification to optimize injection timing and fuel enrichment calculations. Serious racers and performance tuners rely on mechanical pressure instruments to maintain system integrity during high-boost events where electrical systems may experience voltage fluctuation. Installation requires direct 1/8-inch NPT port connection to the nitrous bottle—ensure proper braided steel line routing and vibration isolation to maximize gauge longevity and accuracy in high-vibration environments. Compatible with both wet and dry nitrous setups, this AutoMeter gauge delivers the durability and precision expected in professional racing programs and street performance builds.
