Actually the the cap you need for the fresh water is Flair-it cap cap. Probably 1/2 inch. The fitting is made by Flair-it and pex slipsover the end with the proper Flair-it nut to tighten the pex to the fitting. The Flair-it cap is used when the tubing and nut are removed or not used. The shape of the inside of the cap is made to seal against the barb on the fitting.
