I use a 1/4" NPT tap and a 7/16 drill bit for those barbs. I am pretty sure the chart linked will back that up. |

so on 1/2 x 1/4 npt..the "1/4 npt" refers to the tap size that would be needed to tap a hole? is 1/4" the radius size?
imma have to go back to home depot cuz i asked for a 1/2" npt i bought a 1/2-14 NPT 45/65 tap...and it dosent fit into my tapwrench, but my tapwrench is capable of handling 1/4"-1/2" taps...im confused |

you need the second tap. standard shank will do, long shank is for deep holes. Isn't nice when the cheaper stuff works out?

My 5/8" (barbed end) X 1/2" (threaded) have 14 threads per inch. I'm pretty sure the threads per inch have to be the same or else you will get cross threading.

No. This is my first system, which is not complete. But I have tried slightly to screw a 14 TPI fitting into a 18 TPI dye. It dosn't work nor did I espect it to.

Machine screw sizes:4-40, 6-32, 8-32, 10-24, 10-32 and 12-24
what do those numbers mean? |

Don't take my absolute word for it, cause it's been a year since I used the knowledge. But I believe the first # is threads per inch, and the 2nd is the size (you look at a chart to see what actual size the 2nd # translates to, so you know the size to drill the hole).
Someone please correct the cheeseball if he is wrong! |

Correcting... The first number is the size, the second is the TPI.
