Cast Iron Threaded Flange

This Anvil 0308003201 flange connects a three-inch nominal pipe to a flanged joint using female NPT threads. It is intended for plumbing installers who need a Class 125 rated drain component in a drainage or low-pressure piping system.

Installation notes

The flange arrives faced and drilled with four bolt holes for direct alignment to a mating flange. Cast iron construction requires proper gasket selection and bolt torque to prevent cracking; over-tightening or mismatched flange faces are the most common causes of leaks.

Pressure and temperature limits

The part carries a maximum operating pressure of 175 psi and a service range from minus 20 degrees to 150 degrees Fahrenheit. Systems that exceed either limit will need a higher-class fitting.

Questions about this item

How do I confirm the 3 in nominal pipe size flange is sealing correctly after installation?

Pressurise the line up to 175 psi and inspect the faced and drilled joint for leaks; the cast iron body is rated from -20 to 150 °F.

What comes with the Anvil 0308003201 and what must I source separately?

The box contains the faced and drilled Class 125 flange only; bolts, gaskets and pipe thread sealant are not included.

Which Class 125 cast iron threaded flange should I select for a 3 in nominal pipe size system?

Choose the 0308003201 model; it matches 3 in nominal pipe size, 7 1/2 in flange outside diameter and four bolt holes.
