I think the Danco black braided hoses are worth their higher price for their 
better flexibility: The adapter is 1/4" NPT to 3/8" compression, plus a 
plastic ferrule to replace the included brass one. The hose end is NPS, 
straight thread that seals with a washer but it fits NPT tapered pipe 
threads.

For tubing the nominal size equals measured outer diameter. For pipe the 
nominal size won't be measured anywhere, it's a relic of pipe made from 
weaker wrought iron with thicker walls. Lamp fittings, electrical conduit 
and chain link fence posts are all based on pipe sizes so their dimensions 
aren't common fractions.

I was in line at an industrial supply house behind an inventor who was 
picking up a 2" inside diameter thrust bearing he had ordered to go on 2" 
water pipe, for a tracking solar array. He was very upset to discover that 
2" pipe is actually 2-3/8" outside diameter.
