Sounds like the tubing used for Reverse Osmosis equipment for
preparing tap water for use in Marine aquariums. All rated at mains
pressure using a plastic compression connector system.
It's about 1/4" external diameter. You can get couplers for it also.
Try a specialist who sells Marine fish - not just tropical.

I'expected it to conform to some kind of standard, because the first thing
it connects to is the water filter. There is a coupler between two pieces
of tubing half way up the back of the fridge (on it's way to the icemaker),
but Whirlpool's parts department seems incapable of sending me one of those
:-(
