what is my fitting size

[calvo]

alright just a quick question.
I have a nitrous works wet kit and I need to know what size the small fitting is on the line that goes from the solenoid (-4an) to the spray nozzle (smaller fitting size=?) I can fit a size 7/16 wrench on it.
I need to know if its an -3an or a npt size?

thanks

You may have to contact Nitrous Works on this one.

I believe mine on my 5176 Kit (NOS) were both
-4an.

Another option may be a local autoparts store just take it with you and see what fits!

I'm not familiar with nitrous works.

-6 an to 3/8?
-8 an to 1/2?

I tried a search on google but didn't come up w/ it. I'm still looking

I think my opps are -3AN or 1/8NPT or 1/4NPT
but not sure it it could be something else

3an on the nozzles. Usually 4 an at the bottle connector.

yes I ordered the -4 to -3 line it came in today its was the correct one.
thanks for all your help
