Manifold Hose Nipple removal

[COPO 70 RS/Z28]

Does anyone have any tips on trying to remove a hose nipple from an aluminum manifold.. Or is it just hold you breath and twist!!!!

I would heat the aluminum up well before removal. It will expand and make removal easier and less damaging.

Is there any danger of melting with propane

I use Mapp gas and have never had a problem. I think Mapp Gas is hotter.

FWIW, sometimes tightening a pipe fitting first will expand the hole making loosening it easier.

You need some canning parafin (wax). If you don't have any handy, you should be able to find it at just about any grocery store.

Carefully heat the fitting with MAP gas or propane, just don't get carried away.

Once it's hot, apply some canning parafin to the base of the fitting where it threads into the manifold. The heat will cause the parafin to melt and wick itself down into the threads where it will act as a lubricant to ease dis-assembly. Might take a couple of trys, but it works.

Ill Give it a try, It looks like who ever installed the Nipple (long long ago ) Many have used some form of brown colored compound.

Maybe form a gasket ???????????????

Ooooooo.....that's nasty stuff to work with if it's the one that sets up hard.

Good luck!
