What is the water line tubing made of?

Hi, I have a 1988 Southwind. I have a leaking water valve, that dumps the freshwater tank. It is gray, some sort of plastic. My water lines are of the same gray material it seems, and has silver (aluminum?) ring crimp type connectors that look like the PEX Copper ring crimps. But, unlike PEX, the water line is pretty rigid. It strikes me that PEX wasn't around in 1988, so this is possibly something else. Not sure what it is, though, with the rings crimped on.

Can anyone tell me what it is? And, before I cut into it, whether or not the PEX crimps should work on it - I plan to replace the valve, with a PEX valve, and will be putting a PEX union in, to make it easier next time, since I have to cut out the plumbing to work on this valve.

Any help would be appreciated!
