AN fitting help (Nitrous)
I am putting together my nitrous/nano kit. But the problem I'm having right now is with fittings. The Nano kit came with a bottle valve that the kit obviously fits to, but it doesn't have enough ports so Im using my NOS "super high flow valve". The only problem with this is that the check valve running from the nano kit to the bottle uses a 4AN thread. My valve has larger ports, but smaller than 6AN. I have been trying to see if it's 5AN or something, but that does't seem to be a size that is made.
Anyone know what the ports are on the NOS valve? The check valve is 6AN where the hose from the Nano line connects, then it goes to a smaller size (5AN?) then to 4AN. Maybe its NPT sizes or something. Its just hard to figure out the threads.

Looks like 1/4 pipe thread on the bottle valve. Are you sure the hose is not a 6an for the NANO?

I actually just got it figured out and ordered what I need. The inlet on the nos valve is 1/4 npt, and so is the female end of the check valve . The system is 6AN, but connects to a check valve that is 1/4 female to 1/8 male. But I needed 1/4 male to 1/4 female. Anyways I ordered it, should be good now. Thanks for the help.

The hose is strange too actually. It is a small line that would typically have 4AN fittings, but they have 6AN. But that wasn't the problem. Just the outlet of the check valve. I guess they use 1/8" ports on their bottle valves, so thats what they put in the kit. I just needed to make the outlet 1/4" to fit my nos valve. Much simpler than I thought. Just had me scratching my head for awhile.
