Product Description

The Nitrous Express 15598 Nitrous Oxide Purge Valve Kit is a universal purge system accessory designed to improve the performance and consistency of nitrous systems used in high-performance and racing applications. By purging trapped air and gaseous nitrous from the main feed line before activation, this kit ensures that only liquid nitrous reaches the solenoid, allowing for harder launches and more consistent system response.

This complete kit includes a Lightning purge solenoid, 4AN manifold fittings, a push-button activation switch, and a vent tube to direct purged nitrous safely away from the engine bay. Designed for easy integration into most standard nitrous systems, the 15598 purge valve kit is ideal for enthusiasts seeking improved launch performance, smoother power delivery, and greater control over nitrous purge cycles.
