ya I bought a 3/8" one but NPT was nowhere to be found on any of them . only one with finer thread and one with wider. mine only says 3/8 on the side . thats it.

Like micheal_97 said ...its 3/8 npt. You should be able to just look at it to know the difference (the threads are tapered). This should help.
npt (national pipe thread) Tapered threads both join and seal. The deeper you drive them, the tighter the seal.
National Standard Free-Fitting Straight Mechanical Pipe Thread (NPSM) - a straight thread Straight threads only provide a mechanical junction. They don't really seal.

I went to Home Depot to get my fittings. I just went to the brass fittings in the plumbing section. Its 3/8" NPT threads, get a female T, male coupling, (3/8 male to 3/8 male with the nut in the middle), and then whatever your feed line hooks up to, (i got a 3/8 NPT male to 3/8 barb).
