I tried this to connect a 1-1/4" plastic siphon to a 1-1/2" steel drain and it didn't fit either side. as expected despite the confirmation of these measurements and materials on the clutch page and in the Revain list. Both ends were about 1/4 inch larger than advertised, so it's completely useless to me. It may have been measured for the inside diameter of thicker pipes, but if so it would be nice to have it in the product. Designation.
