I have some water-cooling fittings that I don't need anymore. I did some maintenance and upgraded some parts. They are clean, no red dye was used (but you should clean them before installing them in your system anyways) and new O rings are included. These are all for soft tubing, not hard tubing. Prices marked. (QTY: 01) 3/8"ID x 1/2"OD ( 10mm x 13mm) Koolance Compression Fittings $6/each I will update the list as best as possible, too many pictures to post. U.P.U./Local/Cash only/will only reserve once we confirm a time to meet, this ad has been placed on other websites ( more picture options) if the ad is up, then it's still available. Low ballers will be ignored, ( "no better deal"), if you are doing a water cooling setup, then you know how much these parts retail, if you don't want to spend the money, then water cooling isn't for you. If interested email or call/text me
