Can't find the fitting I need
 

Can't find the fitting I need. I buggerd the threads on the fitting that comes with the NX purge kit. It's the one that you use to connect the purge valve to the nitrous valve. I've found some sites that sell fittings, but I'm not sure what size it is.

if its the one im thinking of it should be a 1/8 npt to 1/8 npt male to male...looks like this? https://static.summitracing.com/glob...os-17500_w.jpg

cyipher is correct, its an 1/8 NPT x 1/8NPT male union. You should be able to find it locally at any store that carries pipe fittings. More than likely if you find it locally it will be made out of brass, which is ok to use. To get it made out of alumimun or the one like the NX purge kits includes you'll probably have to order it. Also, if you have any speed or performance shops locally that carry Earl's or Aeroquip fittings, both of those companies make that fitting in aluminum.

We stock the nickel plated one from NX.
