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 anyway) and new O rings are included. They are from a pet, and smoke free home. I have several ads, so, you can cross-ad pick, too many to list down in one single ad. And if you are looking for an item, that's not listed in my other ads then, I DON'T HAVE IT. But, you can still roll the dice and ask me. 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. Lowballers may get hackled, ( "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. You Pick Up or can deliver for a fee ( and the fee will depend on how far you live)/Local - no shipping/Cash or e-transfer ( once we meet in person)/will only reserve once we confirm a time to meet, this ad has been placed across other platforms. If the ad is up, it's still available.
