Cast Iron Toilet Flange

The OATEY 42255 is a cast iron toilet flange designed for connection to a floor drain. It includes bolts, gaskets, a body and a brass ring for a complete installation kit. The red finish provides visible identification in plumbing systems. Professional plumbers and DIY installers use this component for secure toilet mounting.

Installation characteristics

Cast iron construction delivers durability and stability during normal use without thermal or acoustic concerns typical of powered equipment. The material resists corrosion and mechanical stress in standard plumbing environments. No electrical power draw or noise generation applies to this passive fitting. The included hardware simplifies the assembly process.

Four inch floor drain connection

This flange fits a 4 inch floor drain opening, which is the single specification determining compatibility with the waste pipe. The cast iron body and brass ring create a rigid, sealed junction for the toilet horn. Buyers with differently sized drain pipes cannot use this model. The package supplies all necessary mounting components for that specific diameter.

Questions about this item

How is the 4-inch cast iron flange seated on the floor drain, and what step is often missed?

Place the flange over the drain pipe, compress the included gasket evenly, then tighten the supplied bolts in a cross pattern so the brass ring seats flat; skipping the cross-pattern torque leaves a gap that leaks.

Which part of this assembly will need replacement first during routine maintenance?

The rubber gasket between the flange and drain pipe degrades with age and chemical exposure; keep a spare 4-inch gasket on hand for quick swap-outs.

What limit appears first when the flange sees continuous heavy loads?

The cast iron body handles sustained weight, but the brass ring can deform under extreme point loads, so avoid concentrating force on a single bolt location.
