Fernco 1056-63 – Frequently Asked Questions
1) Can I use the Fernco 1056-63 to connect 6 inch cast iron to 3 inch PVC?
Yes. The ends are rated for cast iron or plastic on both sides, so cast iron to PVC across the reduction is exactly what it's built for. It's the mixed-material case that makes a flexible coupling worth using over a hub adapter, since the sleeve seals on the pipe OD rather than depending on matched fittings.
2) Is the Fernco 1056-63 a shielded coupling or an unshielded one?
The 1056-63 is a flexible sleeve coupling with clamps, not a full stainless shear-band shielded coupling. Unshielded couplings like this are generally used on non-pressure DWV work in accessible or above-ground locations; where local code calls for a shear ring on buried or structurally supported joints, you want a shielded transition coupling instead.
3) Will the Fernco 1056-63 work on a pressure water line?
No. This is a drain, waste and vent fitting for non-pressure gravity flow. For a pressurized water or process line you need a rated pressure coupling or a proper mechanical joint, not an elastomeric DWV sleeve.
4) Do I need anything else to install the Fernco 1056-63 coupling?
The coupling ships as a sleeve with its clamps, so the only tool you need is a torque screwdriver or nut driver for the band screws. Pipe ends need to be cut square and cleaned of scale or burrs before the sleeve goes on, and both pipes should be supported on either side of the joint since a flexible coupling carries no structural load itself.
