2-1/2 in Cast Iron Reducing Flange

This Anvil 0308008200 reducing companion flange connects a 2-1/2 inch threaded pipe to a Class 125 flanged joint. It is built for plumbers and maintenance crews who need a durable cast iron transition in drainage or low-pressure steam systems. The fitting meets ASME B 16.4 and carries UL and FM approvals for code compliance.

Four-bolt pattern with threaded outlet

The flanged end uses a four-hole bolt circle while the opposite end provides an FNPT threaded connection. This combination lets installers join flanged equipment to threaded pipe without extra adapters. Cast iron construction resists corrosion in water and condensate service.

175 psi rating at 150 °F

The fitting handles a maximum pressure of 175 psi from -20 °F up to 150 °F, with a saturated steam limit of 125 psi. Select this flange only when your system design stays within these pressure and temperature boundaries.

Questions about this item

Will the cast iron flange need replacement due to corrosion over time?

The Class 125 cast iron body is rated for 175 psi from -20 to 150 °F and 125 psi saturated steam, so it resists typical plumbing corrosion and should not require scheduled replacement.

What pressure limit is reached first during continuous high-pressure service?

The maximum working pressure is 175 psi at up to 150 °F; saturated steam service is limited to 125 psi, so the steam rating becomes the governing limit in steam applications.

Does the flange generate heat or noise when installed in a constantly pressurised system?

As a static threaded cast iron fitting with no moving parts, it produces no operational noise or heat beyond the fluid temperature, which is rated from -20 to 150 °F.
