Fernco 1051-44 – Frequently Asked Questions
1) What pipe materials does the Fernco 1051-44 coupling join?
The Fernco 1051-44 is a transition coupling that joins 4 inch ductile iron or asbestos cement pipe on one end to 4 inch DWV (PVC drain, waste and vent) pipe on the other. Both ends are 4 inch, so it is a same-size transition between two different pipe materials, not a reducer.
2) Can I use the 1051-44 to connect old cast iron or AC pipe to new PVC in a drain repair?
That is exactly the pairing it is built for. One end takes 4 inch ductile iron or asbestos cement pipe, the other takes 4 inch DWV PVC, so it lets you cut out a failed section of old drain line and splice in new plastic pipe without changing pipe sizes. It is a flexible coupling, so it also absorbs minor misalignment between the two runs.
3) What part number do I order for a 4 inch ductile iron to PVC DWV Fernco transition?
Order Fernco 1051-44. That is the manufacturer part number, and it identifies the 4 inch ductile iron and asbestos cement to 4 inch DWV configuration in the 1051 transition coupling series.
4) Does a Fernco flexible coupling need to be encased in concrete or supported in a trench?
A flexible coupling like the 1051-44 is not a structural member. The pipe on both sides has to be properly bedded and supported so the joint is not carrying load or deflection; the coupling handles the seal and minor alignment differences, not the weight of the line.
5) Do I need anything else to install the Fernco 1051-44?
You need a torque wrench or nut driver to set the clamp bands, and the pipe ends must be cut square and cleaned of scale, tar or loose material before the sleeve goes on. The coupling itself handles the joint; nothing is glued or solvent welded on the PVC side.
