			 I'm not sure where you can get it local, But Ocean Aquatics carries it on there web page http://www.oceanaquatics.com/index.php?cat_id=91&catname='Loc-Line' It comes in 1/2' so no problem there. The adpater screw's into threaded PVC. There is a special tool for working with the stuff. Makes working with it a lot easier but you can mange with out it.
