OATEY 42253 3 in. Cast Iron Flange without Test Cap

The 42253 ships as a complete assembly: cast iron body, brass ring, bolts and gasket. You supply the closet bolts' wax or the toilet seal at set time and the fasteners into the floor, but the flange ring hardware and gasket are already there.

No. The 42253 is the version without a test cap, so there is no knockout plate to pressure-test the drain line through the flange. If your inspection calls for a water or air test at the closet opening, order the test cap version instead.

No lead and oakum or caulking is required. The 42253 seals with the supplied gasket and brass ring, which is why it is described as no-caulk. That makes it a practical repair choice in an occupied unit where a hot pour is not an option.

On an existing cast iron closet bend, a cast iron flange like the 42253 keeps the materials consistent and stands up to repeated toilet resets in high-traffic restrooms. Plastic flanges are for PVC or ABS systems and are lighter but more prone to cracking around the bolt slots. Since the 42253 seals with a gasket and brass ring rather than caulking, you get the cast iron body without the lead-and-oakum labor.

It weighs 4.1 pounds and takes up about 0.098 cubic feet of volume. For a property manager stocking a truck or a van, that is a compact item, and the cast iron mass is what gives it more durability underfoot than a PVC or ABS flange.

Oatey part number 42253, UPC 038753422534. Distributors ordering the test-cap version should note that is a different Oatey number; 42253 is specifically the no-test-cap build.
