Creating a Humidor Control Box
March 13, 2013
Because some of our boards need to be re-humidified after reflow, we decided to make our own humidor. This tutorial will focus on how to model a project in 3D and then fabricate it using a CNC routing machine.

I think you're right about this.

NPT thread standard calls for 18 threads per inch for a 1/4" pipe. These have 20 threads per inch. I would say it is definitely not a 1/4" NPT, but close enough because the threads are plastic and not metal.

A 1/4" NPT fitting is spec'd for 18 TPI, these have 20 TPI. I'm holding a pitch gauge right now. They are 1/2"-20 with a taper. Is it a 1/16" inch taper per inch? I don't know. My guess is that they (China) took a stab at the manufacturing and came out with this.
I'm referencing this chart.
