Just use hydraulic hose with a 1/2" NPT X 45˚ or 90˚ end swedged on by the hose shop. If you don't trust me on the 1/2", take one off one weekend and match the plug at the hydraulic store during the week and you'll be ready by the next weekend. It is easy and a lot cheaper that inventing a complicated solution. Whatever you do, DO NOT attempt to do this with a hard brass pipe and fittings. The vibration from 3116/3126 engines.......and by diesel standards they are very smooth running engines.......will cause the pipe fittings to crack and break at the threads. The first fitting at the transmission needs to be the hydraulic hose. It attentuates the vibration so the rest of your invention can be about anything suitable for hot hydraulic oil.
