Perhaps we are calling the same thing different names - I am remembering
a brass collar which slides over the plastic tube - the collar itself
strikes me as having been a compression fitting; the tube, less so. If
I am wrong in my assessment of this collar as sealing in compression, I
regret the choice of description. Regardless, a tiny collar exists on a
tiny tube, and is squeezed by a tiny nut against a tiny fitting on a
comparatively enormous engine block in a tiny car, which in my case, is
in a tiny garage, covered by a gigantic tarp.

Alas, I have murked up every word, it seems!- the tube and what I am
calling a compression fitting or collar in these repair kits are of a
standard ( or at least, workably compatible ) size, ( or have proven to
have been, in my experience ), not the actual nut. In every case ( 3 ),
I have reused the nuts at both ends without problem.
Alas, given that this path now seems fraught with danger, I retract my
support therefor, and henceforth, ( effective immediately ), vehemently
urge no reader to follow this course, on pain of terrible and sudden
demise!
