Had to choose between a 3/8 wall tube or a 1/2 inch for a high-pressure feed line repair. Went with the 3/8 and it's holding, but I'm still second-guessing it.

Hold up, you used a 3/8 TUBE for a high-pressure line? That's wild. Tube is measured by the outside diameter, so the wall is crazy thin. For pressure you almost always want PIPE, which is sized by the inside diameter. The fact it's holding is pure luck, man. You should really swap that out for schedule 80 pipe at the very least. That's a serious safety risk.

Actually, tube wall thickness varies a lot by schedule, so it's not always thin. You can get high-pressure rated tubing if it's the right spec. The key is the pressure rating stamped on it, not just pipe vs tube.
