You are purchasing a new Gray T-connector that will work with a Bestway or Coleman pool that is 15 feet in diameter and 42 inch deep. Just verify that your current T-connectors have the number 15 on them like what is shown in the listing pictures and has holes that go all the way through the T-connector where the horizontal arms attach. 

Let me know if you have any other questions. I have many other pool parts for this and other type of above ground pools so check out my other listings if you need other parts. We can gladly do combined shipping on most pool parts to help reduce your shipping costs.
