Fernco 1056-55 – Frequently Asked Questions
1) What size pipe does the Fernco 1056-55 flexible coupling join?
The Fernco 1056-55 is a 5 inch by 5 inch coupling, so it joins 5 inch pipe to 5 inch pipe of the same nominal size. If either side of your connection is a different diameter, you need a reducing coupling instead, not this one.
2) Can I use the Fernco 1056-55 to tie two different pipe materials together on a 5 inch drain line?
Yes, that is the normal use for a Fernco flexible compression coupling. Because it seals on the outside of the pipe rather than solvent welding or threading, it connects dissimilar materials on a 5 inch line as long as both ends are 5 inch pipe. Match the coupling to the actual outside diameter of what you are joining, since 5 inch cast iron, clay and plastic do not all share the same OD.
3) Is the Fernco 1056-55 a compression coupling or a shielded no-hub coupling?
It is a flexible PVC compression coupling. A compression style like the 1056-55 seals with a flexible sleeve and clamps and is used for straight repair and connection work in drain, waste and vent lines. If your job calls for a shielded, stainless steel banded coupling to meet a structural or above-ground support requirement, that is a different product family.
4) What do I need besides the coupling to finish a 5 inch Fernco repair?
Nothing gets glued or primed. The 1056-55 is a mechanical connection, so you need a nut driver or torque wrench for the clamp screws and clean, square cut pipe ends on both sides. No solvent cement, no heat, no threading.
5) What is the Fernco part number for the 5 inch by 5 inch flexible coupling?
The manufacturer part number is 1056-55. The 1056 prefix is Fernco's flexible PVC compression coupling series and the 55 identifies the 5 inch by 5 inch same-size configuration, which is what distributors should order against.
