Anvil Cast Iron 90 Degree Elbow

The Anvil 0300001807 is a cast iron 90 degree elbow rated Class 125 for Schedule 40 pipe. It connects two 2 1/2 inch female NPT threads in drainage and trap installations. The fitting suits plumbers and maintenance crews joining horizontal to vertical runs. Buyers needing other angles, sizes or materials should select a different fitting.

Replaces worn or damaged cast iron elbows

This elbow replaces an existing Class 125 cast iron 90 degree fitting with 2 1/2 inch female NPT ends. The upgrade is worth it when the old fitting leaks, cracks or no longer meets the 175 psi at 150 degrees F rating. It does not adapt to different thread standards, pipe schedules or pressure classes.

Limited to Class 125 cast iron pressure rating

The fitting handles 175 psi maximum operating pressure at 150 degrees F per its Class 125 rating. It is restricted to Schedule 40 pipe and female NPT threads only. Installations requiring higher pressure classes, different schedules or male threads cannot use this elbow.

Questions about this item

What pipe size and thread type does the 2-1/2 in female NPT connection require?

The elbow accepts Schedule 40 pipe with a 2-1/2 in male NPT thread on each end.

How do I seal the NPT threads during installation and what is the common mistake?

Apply PTFE tape or pipe dope to the male threads only; the common error is over-tightening past two to three turns past hand-tight, which can crack the cast iron.

When should the elbow be replaced given its 175 psi at 150 °F rating?

Replace it if you see external rust weeping, cracks near the threads, or if system pressure regularly exceeds the Class 125 limit.
