Rheem 480V 5000W heating element

The Rheem SP10873NL is a copper-sheathed immersion element rated at 480V AC and 5000W for commercial or industrial water heaters. It uses a threaded NPSM pipe mount and has an insert length of 13.88 in. The medium watt density rating suits standard-duty heating cycles in compatible tanks.

Replaces failed threaded elements

This unit replaces a worn or scaled element of the same voltage, wattage, thread type and insert length. The jump is worth it when the original copper sheath has corroded or when mineral build-up has reduced heat transfer and recovery time. It restores rated output without changing wiring or controls.

Fits NPSM-threaded heater ports

The element threads directly into an NPSM port on the heater vessel, requiring no flange adapter or gasket change. Copper sheath construction withstands typical potable-water chemistry and frees up the flange positions for anodes or sensors. Verify the tank’s voltage and port thread before installation.

Questions about this item

What thread type and insert length does the Rheem SP10873NL element need for the mounting opening?

It uses an NPSM threaded pipe mount with a 13.88 in insert length, so the tank port must match that thread and depth.

How do I install the 480V 5000W element correctly, and what step is often missed?

Shut off power and drain the tank, apply thread sealant on the NPSM threads, tighten the element, refill completely before restoring power to avoid dry-firing.

When will the copper sheath on this 5000W element need replacement?

The copper sheath lasts until mineral scale buildup or corrosion reduces heating efficiency; inspect annually and replace if scaling or pitting appears.
