Fernco 1059-150 – Frequently Asked Questions
1) What size pipe does the Fernco 1059-150 flexible coupling fit?
The 1059-150 is a 1-1/2 inch flexible coupling, so it joins 1-1/2 inch pipe on both ends. It is a straight, same-size coupling rather than a reducer, so if you are transitioning from 1-1/2 inch down to a smaller line you need a reducing model instead.
2) What is the pressure rating on the Fernco 1059-150 coupling, and can I use it on a pressurized water line?
It is rated 4.3 psi, which is a drain, waste and vent rating, not a supply rating. Use it on gravity DWV piping only. Anything on a pressurized potable or hydronic line needs a rated pressure fitting, not a flexible clamp coupling.
3) Do I need anything besides the Fernco 1059-150 to make the joint, or does it come with clamps?
It is a clamp coupling, so the stainless clamps come assembled on the black sleeve. You need nothing but a nut driver or socket to tighten them. No primer, no cement, no gasket lube required, which is why plumbers reach for these on repairs where the pipe ends cannot be rotated.
4) Can a Fernco flexible coupling be used to join two different pipe materials, like PVC to cast iron?
A flexible elastomeric coupling like the 1059-150 seals on the outside diameter of the pipe, so it will bridge dissimilar materials as long as both ends are the size the coupling is built for. This one is a 1-1/2 inch coupling, so both pipe ends have to be 1-1/2 inch OD-compatible. Cast iron, PVC, ABS and copper of the same nominal size all have different outside diameters in some cases, so match the coupling to the actual OD you are clamping.
5) Is the Fernco 1059-150 approved for buried or concealed installation?
Flexible couplings of this type are generally kept accessible, and many inspectors do not allow a clamp coupling behind a finished wall or under a slab. Confirm with your local code official for the job before you bury or conceal it. What the 1059-150 is straightforwardly right for is an accessible repair or a fixture connection in a 1-1/2 inch DWV line.
6) What part number do I order for a 1-1/2 inch Fernco black flexible clamp coupling?
Fernco part number 1059-150. The 1059 series prefix identifies the coupling family and the 150 suffix is the 1-1/2 inch size. The sleeve is black.
