3-inch Cast Iron Blind Flange

The Anvil 0308016401 is a Class 125 blind flange designed to terminate a 3-inch nominal pipe run. It is made from cast iron and carries a 175 psi maximum operating pressure rating. Mechanical contractors and maintenance teams use it to seal flanged piping systems in commercial and industrial installations.

Verify flange class and bolt pattern

Confirm that the mating flanges are also Class 125 so the bolt circles align correctly. The flange has four bolt holes and a 7 1/2 inch outside diameter. Check that your gasket material is suitable for the -20 to 150 degrees F service temperature range before assembly.

Replaces damaged or missing blind flanges

This component upgrades a system by providing a new, faced and drilled sealing point where an old flange has corroded or been removed. The jump is worth it when pressure testing requires a reliable blank-off that meets the Class 125 pressure rating without machining a custom plate.

Questions about this item

What components are included with the Anvil 0308016401 flange and which installation hardware must be purchased separately?

The flange itself is supplied faced and drilled with four bolt holes; bolts, nuts, gaskets and any pipe sections are not included and must be sourced separately.

How do I decide between the available pressure-class options for this cast-iron blind flange?

This model is offered only in Class 125 rated for 175 psi maximum operating pressure; choose it when your system design requires that specific class and pressure limit.

What does the 175 psi rating mean for daily operation in a heating or cooling loop?

It indicates the flange can safely handle continuous internal pressures up to 175 psi within the -20 °F to 150 °F temperature range stated for the cast-iron body.
