Rubber Washers For Plumbing 40mm 10pcs, Sink Plug Rubber Seal Cone O-Ring Silicone Washer For Water Pipe Sink Pipe Fittings For 1/2 Inch Drain Pipe Odour Trap Siphon

ok

I needed these seals to replace some old ones that had gone on some old pipes. There is no specific indication for these seals, and it seemed like just generic rubber seal. The diameter is accurate, but the image is misleading I guess and they came a lot taller than I thought, and I had to slice them thin. After slicing they worked perfectly. They come in a small cardboard box well protected.

Work very well.. leak stopped

These are exactly what I needed to fix the leaky waste pipe under the kitchen sink. They look small but provide a snug fit, perfect for preventing any backflow. Job done 👍
