OATEY 42255 – Frequently Asked Questions

1) What comes in the box with the Oatey 42255 4 inch cast iron closet flange?
The 42255 ships as a complete assembly: cast iron body, brass ring, closet bolts and gasket. You do not need to buy a separate bolt kit or gasket to set the toilet. What it does not include is a test cap, so if your rough-in inspection calls for a capped riser you need the test-cap version instead.
2) Do I need to caulk or lead the joint when installing the Oatey 42255 flange?
No caulking is required. The 42255 uses a gasketed connection at the toilet flange rather than a poured lead and oakum joint, so it sets without hot work or caulking compound.
3) Should I order the flange with the test cap or without for new construction?
For new construction where the DWV system has to be pressure or water tested before the toilet is set, order the version with a test cap, because the cap seals the riser for the test and is knocked out afterward. The 42255 is the version without a test cap, which suits replacement work and remodels on an existing, already tested drain.
4) Is a cast iron closet flange worth it over a plastic one for commercial or multi-family work?
Cast iron is the choice where the closet bend is already cast iron and where the fixture sees heavy public traffic. The 42255 weighs 3.4 pounds and uses a brass ring for the bolt slots, so the bolt bearing surface will not deform or crack the way a thin plastic ring can when a toilet is overtightened or rocked. On a PVC system with light residential use, a plastic flange is the simpler match.
5) Which Oatey part number do I order for the 4 inch cast iron flange with no test cap?
Order Oatey 42255. That part number is the 4 inch cast iron closet flange supplied without a test cap, including the brass ring, bolts and gasket.
