Looking for a Kitchen Sink Hole Cover with a opening
Buy a 1-3/4-Inch Sink Hole Cover and drill a hole in the middle. voila problem solved. 

You may want to get a grommet to protect the hose from the edge of the hole you are drilling. You would need a grommet with a hole sized right for your pipe and then drill the appropriate size hole for the grommet to fit in.
