Nitrous Express 15510 Flo-Thru Nitrous Pressure Gauge 0-1500 PSI 6AN Manifold

Vehicle Fitment

• Universal - Compatible with any nitrous oxide system running a 6AN nitrous supply line requiring inline pressure monitoring

Fitment Notes

• Designed for 6AN nitrous lines - for 4AN applications, see Nitrous Express part 15509
• Manifold installs inline in the nitrous feed line - the nitrous flows through the manifold while the gauge monitors pressure simultaneously
• Both manifold ports are 1/8" NPT - one accepts the gauge, the other can accept a purge valve, pressure switch, or additional accessory; unused port uses the included 1/8" NPT plug
• Sold as a complete kit - one gauge and one manifold assembly per purchase

Features

• High-accuracy, liquid-filled mechanical gauge reads nitrous bottle pressure from 0 to 1,500 PSI
• 2-1/16-inch gauge diameter provides clear, easy-to-read pressure display at a glance
• Color-coded gauge face allows faster pressure confirmation without needing to read specific numbers
• Flo-Thru design - nitrous passes through the billet aluminum manifold and continues to the system rather than dead-ending at the gauge, preventing pressure loss issues
• CNC-machined billet aluminum 6AN manifold with two 1/8" NPT ports for gauge and secondary accessory connection
• Liquid-filled gauge construction dampens needle fluctuation for a stable, accurate reading under vibration

Product Description

The Nitrous Express 15510 is a complete Flo-Thru nitrous pressure gauge kit that combines a high-accuracy 2-1/16-inch mechanical gauge with a CNC-machined billet aluminum 6AN manifold for clean, reliable inline pressure monitoring. Unlike a simple tee fitting that dead-ends at a gauge, the Flo-Thru manifold design allows nitrous to pass directly through the manifold assembly and continue to the system - eliminating the potential for trapped pressure or inaccurate readings caused by a no-flow condition at the gauge connection. This is particularly important during purge cycles and system priming where accurate live bottle pressure feedback is critical.

The liquid-filled mechanical gauge reads from 0 to 1,500 PSI with a color-coded face that allows the operator to confirm pressure status at a glance without taking attention off the track. Two 1/8" NPT ports in the manifold provide versatility - one mounts the gauge, and the second can accept a purge valve, pressure switch, or any other 1/8" NPT accessory. An NPT plug is included for the secondary port when not in use. The 15510 is the 6AN version of this kit; for 4AN systems, see Nitrous Express part 15509. As a universal fit product, it integrates cleanly into any existing nitrous setup.
