Nitrous Express 15540 4-Inch Liquid-Filled Nitrous Pressure Gauge

The Nitrous Express 15540 is a professional-grade 4-inch liquid-filled nitrous pressure gauge designed for high accuracy and reliability in nitrous oxide system monitoring. The liquid-filled design dampens needle vibration and provides clear, stable readings even in high-vibration racing environments.

Key Features:

• 4-inch diameter face for easy visibility and precise reading
• Liquid-filled construction reduces needle flutter and enhances durability
• High-accuracy pressure monitoring specifically calibrated for nitrous oxide systems
• Direct-mount 1/8" NPT fitting integrated into the gauge body eliminates the need for additional adapters
• Simplified installation - mounts directly into inline adapters without extra fittings
• Professional-grade construction for racing and performance applications

This gauge provides the accurate pressure monitoring essential for optimizing nitrous oxide system performance and safety. The integrated NPT fitting streamlines installation and reduces potential leak points compared to gauges requiring separate mounting hardware.
