This is a set of single pipe joint fittings. These are used items, but I'm selling only the ones that are usable after disassembling them. There are some scratches and spray paint residue, but they can be used without any problems. The adjusters had rubber on the bottom, but it had deteriorated, so I removed it. Please make your judgment based on the photos. These are used items, so please refrain from purchasing if you are sensitive to such things.
