1-Inch Cast Iron Drain Elbow

This 90-degree elbow connects two 1-inch female NPT threads in drainage systems. The Class 125 cast iron body suits Schedule 40 piping in residential or light-commercial plumbing. It is a straightforward fitting for redirecting waste lines where a right-angle turn is required.

Pressure Rating at Elevated Temperature

The fitting withstands 175 psi at 150 degrees F, so it maintains seal integrity when hot water or condensate passes through continuously. Cast iron construction resists deformation under sustained thermal cycling better than thinner-walled alternatives. This rating applies to steady-state conditions rather than momentary spikes.

Verify Thread Compatibility and Local Codes

Confirm that both mating pipes are 1-inch female NPT before ordering. Some jurisdictions restrict cast iron drain components, so check local plumbing codes for acceptance. The part is supplied new and ready for installation with standard pipe sealant or tape.

Questions about this item

Does the cast-iron elbow radiate much heat when carrying 150 °F water continuously?

The fitting is rated for 175 psi at 150 °F, so it handles that temperature without degrading, though the iron will become warm to the touch.

What pipe and thread type must I already have to connect this 1 inch FNPT elbow?

You need Schedule 40 pipe with 1 inch male NPT threads on both ends to screw into the female threaded ports.

Will this Class 125 cast-iron elbow mate with older galvanized steel pipe threads?

Yes, the 1 inch FNPT threads follow the same NPT standard used on legacy galvanized pipe, so they engage directly.
