Combines JB Weld

You could try cutting a 2 inch piece of heater hose to go around the line (cut it so that it goes not quite around)and use a good hose clamp right over the hole, this has worked for me on a line of about 2450 psi and a pin hole, if its a crack any wider than the hose clamp no good.

You can get brass compression fittings at you hardware or autoparts store. Just cut the line with a hacksaw or tubing cutter then slide the nut and ferule oneach side. Put the fitting in between an tighten it up. Be sure to sand the paint off the line.

It never worked for me on any job.

I have a piece of metal hydraulic line on a 7080 that has been holding for about six years. I removed the line, then heateated it to burn off all the fluid and paint. I mixed the JB Weld as per the instructions and then applied it to the leaking area. The line was re-installed the next day. I have not had a problem yet with the repair. As for me it worked this and other times that I decided to use it. This is probably the most extreme situation in which I have used JB Weld.
