[PSUBS-MAILIST] Mineral Oil substitutes

[Alan via Personal_Submersibles]

Brian,
I have clear vinyl tubing & it's quite soft, but it's in a fixed position.
Maybe some sort of hydraulic line with a swivel join?
BTW Greg was finding that some of his plastics in his motor were turning
brittle from his compensating oil.

I would actually like to find something to soften those vinyl lines !  they are so stiff .  Actually would probably be better to find a more flexible tubing , just to make turning the motors a bit easier .
