brazing a hydraulic line

[coloradotrout]

Lower line disconnected. I used compressed air to clear the line of most fluid. The other end is attached to the tractor. I think I can get a torch and brazing rod in position.

Is mapp gas hot enough?

The leak is tiny and somewhere around the perimeter of the line to fitting connection. I watched for minutes and couldn't exactly pinpoint. At just idle it produces a drip once a minute or so. Under load - using the FEL, for example, it leaks much more.

It needs to be clean, you'll have to clean out the inside with solvent and keep oil from getting to the joint. Otherwise it can wick the oil up into the joint and could male things worse.

Once cleaned inside and out with solvent (brake clean, acetone) heat it with the torch to cook any remaining junk out.
