Anvil 2 in Cast Iron Reducing Flange

This Anvil 0308008804 cast iron reducing companion flange connects a 2 in nominal pipe to a flanged joint in plumbing systems. It is built for installers who need a durable, threaded transition fitting rated for Class 125 service. The flange suits commercial and residential drainage installations where cast iron piping is specified.

Class 125 pressure rating

The single specification that decides fit is the Class 125 rating with a 175 psi maximum operating pressure. This pressure class determines whether the flange matches the piping schedule and system design pressure. Installers must verify that the connected piping and bolting also meet Class 125 requirements for a compliant assembly.

Sustained temperature and pressure performance

Under continuous service the flange operates reliably from -20 degrees to 150 degrees F at its rated 175 psi. The cast iron body maintains its seal and structural integrity across this full temperature span without the pressure derating that can occur in short-term test conditions. The eight bolt holes distribute clamping force evenly for long-term joint stability.

Questions about this item

How does the Class 125 rating affect pressure handling in a working system?

Class 125 means the flange is rated for 175 psi maximum operating pressure, so it will hold that pressure in service without leaking.

What does the FNPT connection mean for pipe compatibility?

The flanged-by-FNPT end accepts female National Pipe Thread fittings, letting you thread standard NPT pipe directly into the flange.

What bolt pattern is needed to mount this 9 in flange?

The 9 in outside diameter flange has eight bolt holes spaced to match the Class 125 drilling pattern for standard companion flanges.
