Fernco 1056-32 1056-32 3 in. x 2 in. Flexible PVC Clamp Reducer Coupling

The Fernco 1056-32 is a reducing coupling that joins a 3 inch line to a 2 inch line. It is a flexible PVC coupling with clamps on both ends, so the larger end goes over the 3 inch pipe and the smaller end over the 2 inch pipe. If both of your pipes are the same size, you want a straight coupling instead of this reducer.

Order Fernco 1056-32. That manufacturer part number is the 3 inch by 2 inch flexible PVC clamp reducer coupling. The trailing 32 in the number tracks the size step, 3 inch down to 2 inch.

No extra bands needed. The 1056-32 is a clamp-style coupling, so the stainless clamps come attached at both ends of the flexible sleeve. You tighten them onto the pipe with a nut driver or torque wrench. The only thing you supply is the tool.

That is the main reason plumbers reach for a flexible coupling. The sleeve seals on the outside diameter of the pipe rather than threading or solvent welding, so a 3 inch line and a 2 inch line can be joined at that reduction regardless of whether you are working in PVC, ABS, cast iron or clay, as long as the outside diameters fall in the coupling's range. A solvent weld reducing bushing only works PVC to PVC and only where you can take the joint apart or get a fitting hub on it.

Depends on your local code, and that is worth checking before you set the pipe. Many jurisdictions restrict unshielded flexible couplings to accessible locations and require a shielded, banded coupling where the joint is buried or inside a wall. The 1056-32 is the unshielded flexible PVC clamp style, so plan on it being the fix for exposed or accessible work unless your inspector says otherwise.
