Nelson has a good summary which seems to be the same as my experience. Keep in mind that the air hose needs to be installed tipped toward the coupler at a 30 degree angle, not straight down.

I’ve used then since they were first introduced with the Precision Scale bracket. The PS brackets have dimple for starting the bit, but the castings aren’t always complete at the U-bolt, so I ‘ve lost a few by drilling through the side of the U-bolt. Start the hole with a #79 bit, then move up to a #77, then a #76. The air pipe on the air hose sometimes has a casting line with flash that interferes with threading it through the U-bold. I ‘ve cut off the flash with a double edge razor blade, which has a thinner blade and is sharper than a single edge razor blade. If the flash is minimal, I taper the end of the air pipe slightly to get it started while threading it into the U-bolt. I bought some YMW air hose brackets to try, but I haven’t used any yet. The detail is better on PS brackets, but the YMW brackets look like it would be easier to thread the air pipe since the hole is drilled before bending, and the metal isn’t as hard to drill.
Anybody want to buy a large supply of Kadee plastic air hoses cheap?

I have posted this request with the Early Rails Grp already but thought I would ask this grp too. I'm interested in "investing" in Hi Tech HO freight car air hoses and would like to know what experiences people have had with them. I would be equipping about 80 pieces of rolling stock so this would be a significant expenditure in resources. They offer 22" and 26" lengths in HO. I presume the 22" is for earlier eras Any info or insights about them would be appreciated.
