Air Leaks in Copper Tubing

[ccbamatx]

Hello there... new member here.

I just bought a M936A2 from Ft. Hood, TX.

...lots of leaks in the air system.

Questions:

1. What is an easy way to temporarily stop a leak in the copper tubing (hoping to get them all identified at once)?
2. Should I go back with copper, or is there another alternative?

Thanks,

is the leak at the compression fitting? Either crank it down or cut it back and use new compression rings since they smoosh into a tight seal.

If its in the middle they you can cut out that part and use a compression union. Copper is good but most of the system lines are plastic with compression fittings. If you replace it get good line that can handle the PSI and UV.

From the leaks I can feel... they are pin holes I can feel with my finger... like in the copper tubing running to the air horn... etc.

Don't know yet about the ones I can hear under the dash.

There are some epoxies made for copper that may hold for test purpose. Also a piece of rubber (inner tube?) and a hose clamp will also work for testing.

DOT nylon air line is probably the best replacement. Good for everything except high heat areas. You can retain the same fittings you just need new ferrules and inserts. Check this fine post by rustystud.

Go with the DOT plastic air line to replace the old copper. Much cheaper and easier to work with, I replaced a bunch of missing line on my m816.
