hey guys what is the difference between blown down tube and purge kit?
and what is the difference between NX "ice man" purge valves and just a purge valves??
thanks

 

A blow down tube allows the nitrous to excape to the atmosphere outside the vehicle if the pressure in the bottle exceeds the rupture disk pressure (around 3000 psi). Safety measure to prevent you from blowing up.

The purge valve allows the gas in the line from the bottle to the solenoid to escape so you get nothing but pure nitrous liquid to the nozzle.

Ice man is just an NX brand name, sort of like fogger nozzle is to NOS or Kleenex is to tissues.

 

ok it makes sense now thanks
