-6 Nitrous Purge Valve Kit

The Nitrous Express -6 Nitrous Purge Valve Kit is an essential component for any serious nitrous oxide system builder or performance enthusiast looking to optimize fuel and air purging before a hard launch. This compact yet robust purge kit allows you to vent excess fuel and air from the nitrous system lines, ensuring consistent jetting and eliminating the risk of lean conditions on the first hit of spray. Whether you're building a street car, bracket racer, or dedicated drag strip platform, a quality purge valve kit eliminates guesswork and delivers repeatable performance when it matters most.

This kit features a 6 AN thread interface, allowing seamless integration into modern fuel and nitrous plumbing systems with industry-standard AN fittings and hose compatibility. The purge valve assembly includes a solenoid-operated design that vents pressurized lines when activated via a simple push-button control, ensuring complete system purge between passes. The precision-engineered solenoid valve responds instantly to driver input, and the 6 AN fittings deliver reliable flow rates without restriction while maintaining tight seal integrity under pressure. Weighing just 0.6 lbs and measuring 3.5 x 2.3 x 8.8 inches, the compact footprint makes it ideal for tight engine bays where space is at a premium.

Experienced nitrous tuners and dedicated racers benefit most from this kit's repeatable purge capability, which removes the guesswork from pre-launch fuel and air staging. The push-button controller gives drivers complete command over the purge cycle, allowing them to dial in consistent nitrous hits lap after lap without worrying about stale fuel or lean conditions on initial spray. Installation is straightforward for anyone familiar with 6 AN line routing and solenoid integration; the included fittings work with standard braided hose and most aftermarket fuel system configurations. This Nitrous Express purge kit works in tandem with any wet or dry nitrous system running 6 AN feed lines.
