Once tightened on it was good as new with no odor leakage. ### ⭐⭐⭐⭐⭐ Exactly what I needed *by A***M on February 11, 2025* The 1-1/2 inch is a perfect fit on a 1-1/2inch PVC drain pipe. My kitchen drain to the basement isn't on a downward enough slope so it occasionally gets sluggish. We cut the pipe to access it with a snake and hose to flush it through once or twice a year as needed. This works very well for keeping it from leaking and still being able to access it when needed. No glue needed which would have defeated our purpose. It fits snug and did need a little wiggling to put it on. Once the screws on the clamps are tightened it will not budge. We'll see how well it holds up long term, whether the rubber gets hard and cracks etc. Bought a spare since it's not something I could find locally (No big box DIY stores nearby). I can see this being very useful for multiple in a pinch needs. ## Frequently Bought Together - Fernco P1056-150 Flexible PVC Pipe Coupling, Pack of 1, Black - Fernco P1056-150/125 Flexible PVC Pipe Coupling Cast Iron, Plastic or Steel Plumbing Connections, 1-1/2" x 1-1/4", Black - Fernco Inc.
