Product Description

The Nitrous Express 15603 Purge Valve System is a universal accessory designed to enhance nitrous oxide system performance on vehicles using NX Lightning or Iceman solenoids. This purge system effectively clears air and trapped gaseous nitrous from the main feed line before activation, ensuring that liquid nitrous reaches the solenoid quickly for more consistent and powerful launches.

Included in the kit are a high-quality Lightning purge solenoid, a push-button activation switch, appropriate NPT fittings, and vent tubing to route discharge safely away from the engine bay. Designed for simple integration with existing nitrous setups, the 15603 works particularly well when your solenoid has a built-in purge port. Its universal design and robust construction make it suitable for a wide range of high-performance and racing nitrous applications.
