Fernco 1056-33 – Frequently Asked Questions
1) What size pipe does the Fernco 1056-33 flexible coupling fit?
The Fernco 1056-33 is a 3 inch flexible PVC clamp coupling, so it joins 3 inch pipe on both ends. It is a single-size part, model 1056-33, with no other diameters under that number.
2) Do I need to glue or solvent weld the Fernco 1056-33, or does it clamp on?
No solvent cement or primer. The 1056-33 is a clamp-style flexible coupling, so the sleeve slips over the pipe ends and the clamps tighten down to make the joint. That makes it a repair and tie-in fitting you can install in a wet or tight space where you can't get a glued socket to seat.
3) Can I use a Fernco coupling to tie 3 inch PVC into an existing drain line?
That's exactly what it's for. The 1056-33 is a 3 inch flexible coupling used to join or repair drain, waste and vent pipe where you can't rotate or spring the pipe into a rigid fitting. Cut out the damaged section, slide the coupling over each end, and tighten the clamps.
4) Is a flexible coupling the right choice, or should I use a rigid PVC coupling?
Use a rigid solvent weld coupling when both pipe ends are the same material, clean, and you can work them into the socket. Reach for the Fernco 1056-33 when you're cutting into an existing line, working in a trench or crawlspace, or need the joint to absorb a little movement and misalignment. The trade-off: flexible couplings generally need support on either side and are not a substitute for properly bedded pipe.
5) Is the Fernco 1056-33 a pressure fitting or drain only?
Treat it as a non-pressure fitting. The 1056-33 is a 3 inch flexible clamp coupling for gravity drain, waste and vent piping, not for pressurized supply lines.
6) What tool do I need to install the Fernco 1056-33?
A nut driver or a torque wrench sized to the clamp screws is all it takes, plus a saw to square up the pipe ends. No heat, no cement, no special press tool. Square, deburred cuts matter more than anything else here, since the sleeve seals against the outside wall of the pipe.
