Product Identity

The Anvil 0300000601 is a cast iron 90 degree elbow rated Class 125 for plumbing installations. It suits contractors and maintenance teams assembling drainage or low-pressure steam lines that require a standard FNPT threaded connection.

Installation Checklist

Verify that the piping system uses 1/2 inch FNPT threads and operates within a temperature range of -20 to 150 degrees F. Confirm the design pressure does not exceed 175 psi at the lower temperature limit or 125 psi for saturated steam service before fitting this component.

Upgrade Context

This fitting replaces worn or non-compliant elbows in systems built to ASME B16.4 where UL and FM approvals are mandated. The jump is justified when existing fittings lack the documented pressure rating or material traceability required by current inspection standards.

Questions about this item

What comes in the box and do I need any extra fittings for the 1/2 in FNPT connections?

The box contains one cast-iron 90° elbow with 1/2 in FNPT threads. Pipe nipples, sealant or tape for the threaded joints are not included.

How do I decide between the Class 125 rating and a higher-class fitting for my system?

Class 125 supports up to 175 psi at -20 °F to 150 °F and 125 psi saturated steam; choose a higher class only if your design pressure or temperature exceeds those limits.

What does the 175 psi rating at 150 °F mean when the elbow is installed in a real piping run?

It confirms the fitting will safely handle 175 psi water pressure at temperatures up to 150 °F, provided the piping is properly supported and assembled per ASME B16.4.
