Shielded Transition Coupling

The Fernco 1056-53 is a shielded transition coupling designed to join pipes of different nominal sizes. It provides a flexible, watertight seal between drainage system components.

Installers connecting 5 in and 3 in nominal pipes

This coupling suits professionals joining 5-inch and 3-inch nominal pipe diameters in drain, waste and vent systems. It is not for installers working with pipes outside these nominal sizes or those needing a rigid, non-flexible joint.

Nominal pipe size 5 in by 3 in

The coupling fits nominal pipe sizes of 5 inches on one end and 3 inches on the other. This specific size combination determines whether the part matches the installation requirements.

Questions about this item

What nominal pipe sizes must the existing plumbing have for the 1056-53 coupling to connect properly?

The coupling joins a 3-inch nominal pipe on one side and a 5-inch nominal pipe on the other, so both pipe sizes must be present in the drain line.

Will the stainless-steel shield on the 1056-53 interfere with older cast-iron or clay pipe ends?

The shielded design clamps over the outside of each pipe, so it works with cast-iron, clay, PVC or other materials as long as the outer diameters match the 3-inch and 5-inch nominal sizes.

How can I verify the 1056-53 is sealed correctly after tightening the clamps?

Run water through the drain and check the joint; a properly installed coupling shows no leaks at either clamp band or between the shield and pipe surfaces.
