Page 46-07 says to use Lubon #404 or equivalent and to someone who is new to all this how in the world was I suppose to know what equivilant was? I couldnt find anywhere that sold lubon so I ended up getting advice to use Permatex high temp tube thread sealant. Can be bought from places like Auto Zone for about $5. Also permatex form-a-gasket is available from air craft spruce. Hopefully this will help someone newbie like me in the future to figure out what to use.
"Setup the Left and Right Cylinder Assemblies. Apply a thread sealant, such as Lubon #404 or equivalent, to the pipe threads of the AN822-4D Tube/Pipe Elbow before threading them into the top of the Cylinder Assemblies"
