Purging air out of a nitrous line before a run keeps the first hit from being weak and inconsistent, but that only works if the purge solenoid itself opens cleanly every time. This ZEX solenoid uses a stainless body and 1/8 in. NPT ports with an internal filter, built to handle that job without becoming the weak link in the system.

• 1/8 in. NPT female inlet and outlet threads.
• Draws 1.8 amps.
