John Guest Union Conversion Connector - 15mm x 1/2 CTS (5/8 OD)

Exactly what i needed in a part that is not stocked in usual construction or hardware outlets.

Worked!

Works as advertised! On my system, the 15mm is all green, so I was a bit concerned that the 15mm end of this fitting is grey but maybe there isn't a standard color for 15mm PEX. Plugged right in, no leaks, easy fit. Converter is also well labeled so no confusing the ends. Thanks!!

Absolutely perfect. This is a hard item to find in the Marine World.
