PRODUCT DESCRIPTION
The Mainline purge system is designed to purge air from the nitrous lines and allow for immediate system activation. This system includes a stainless steel purge solenoid, an activation button, and a vent tube to expel purged nitrous from the solenoid. It also includes a -6 AN manifold for in-line connection with the nitrous feed line. This allows the system to be purged even if the solenoids do not have an integrated purge port. The purge system can also be used to relieve bottle pressure for optimal nitrous performance every time the system is activated.
The purge system includes:
Mainline purge electrode.
6 AN adapter manifold.
Button activation.
1/8 to 1/8 NPT connection.
1/8 NPT to compression fitting.
7-inch, 3/16" stainless steel tube.
If using a smaller -4 AN feed line, the correct Mainline purge system is PN# ML15600.
