Anvil Malleable Iron Return Bend

The Anvil 0310077201 is a Class 150 open return bend manufactured from malleable iron for drain component assemblies. It provides a directional change in piping systems using a 3/4 inch female NPT connection on each end. This fitting suits installers working with Schedule 40 pipe in standard plumbing applications.

Class 150 Pressure and Temperature Limits

The fitting carries a Class 150 rating with a maximum operating pressure of 300 psi at 150 degrees Fahrenheit. Performance is bound to this pressure and temperature ceiling; systems exceeding either limit require a higher-class component. The Schedule 40 pipe specification defines the compatible wall thickness for the threaded joint.

3/4 Inch NPT Capacity and Headroom

The 3/4 inch female NPT threads accommodate standard Schedule 40 pipe of the same nominal size for typical drainage flow rates. Headroom exists within the 300 psi rating for normal pressure fluctuations in residential or light commercial service. The fitting does not support larger pipe diameters or higher pressure classes without changing the component.

Questions about this item

Which size of this Anvil malleable iron open return bend matches my 3/4 in NPT piping?

The fitting is made in a single 3/4 in female NPT size for Schedule 40 pipe, so there is no alternative version to select.

What does the Class 150 rating mean when the trap is installed in a working system?

Class 150 designates a 300 psi maximum operating pressure at 150 °F, which is the pressure ceiling for this malleable iron bend in service.

How does the NPT thread standard limit what I can connect to this return bend?

Both ends use 3/4 in female NPT threads, so only matching male NPT fittings or pipe nipples will seal correctly; other thread forms will not engage.
