727 return line leak at tranny fitting

At work we use copper or aluminum conical seals to help stop tapered fittings from dripping when they just won't seal no matter how tight they are.

They really do work. I think the trans fitting is 5/16 (-5)

Thanks scatpactbee, I ordered two aluminum and two copper. $1.75 each. Hopefully one of these will work. Now I'm fighting trying to get my steering box out that crapped out on me last week. No fun looks like I'm going to have to pull the exhaust manifold to get it out.:wtf:
