5/16" OD plastic water line 10 feet long- just cut it to fit your needs- plus a 5/16 slip-fit coupling. About 3/16" ID allows excellent flow.  Suitable for use on any refrigerator or other water line applications.

Be sure you are buying the right size! 

I keep this on my service truck to save time and money from buying the OEM version when a line is cracked or damaged.
