Well, yah, sorta, almost print near, but not quite

The operative word is "practical"

Gerald is spot on. In theory its possible, but in the practical world? 
Not likely. He phrased it much better than I.

If you are willing to spend enough and take enough time you could 
probably get a sealed conduit.  Then I have to ask, what would you 
really gain.

IOW, why do we even bother working so hard to keep water out of the 
conduit? If there are no connecter in there and the coax is good, what 
do you gain?

I gave up, don't glue the joints, leave the ends open and don't even 
attempt to keep water out.  I use the conduit for one thing...OK make 
that two things  Protect the coax from mechanical damage and ease of 
installation.  Otherwise I could just leave the cables laying on the ground.
