[PSUBS-MAILIST] Simple oring (or alike) system

[Victor Romero <romero@kde.org>]

	Dear Co-listers,

		Some weeks ago I asked for a propulsion engine for a ROV. We found that 
theres some water pumps that could be fine... but finally I found them not 
strong enought.

		So finally I decided for some electrical Graupner 100w dc motor. But now I 
need some kind of oring or seal. 

		I wonder if there exists some kind of pre-made solution out there, I saw 
some mechanichal seals and so on, but I'm not expertise enought to know if 
there are good enought for a submersible. I'm also considering make my own 
oring with the help of a friends workshop  but I think I'll never going to do 
one good enought to be at more than 5 or 6 bars.

		Thanks in advance.
