Nitrous sizes
 

Ok so this is going to sound dumb I know. But I've been looking through the NX catalog and I see that they have different size hoses and stell braided lines etc. My question is how are these read? For example I want to buy a pressure gauge for the bottle, how do I know what size it is I need? They have D-4 and D-6 for the manifolds of the gauges. And then as far as lines go they have D-3 etc. So how does this go?

Thanks in advance.

They are rated by how much will flow through them. D-4 is used for the nitrous supply line from the bottle to the solenoids. Thats what size you have.

The lines from the solenoids to the nozzle is a D-3. Make sure you are using NX lines because I found out that the NOS braided lines I was using have a smaller inside diameter than the NX hard lines I have now.

When your running ALOT of spray, you have to upgrade everything. Bottle valve has to be able to accept a D-6 supply line. The solenoids have a D-6 inlet and a D-4 outlet to the distribution block that feeds usually 2 or more nozzles depending upon setup.
