Ao Smith 100108346 Screw-in Water Heater Element 240V 3800W

Product Description

The AO SMITH 100108346 is a screw-in electric water heater element designed for residential and light commercial water heating applications. Built with an Incoloy nickel-alloy sheath, this low-watt-density element delivers 3800 watts at 240 volts across a 13.125-inch immersion length. Low-watt-density construction reduces scale buildup and extends service life compared to standard-density elements. A gasket is included, providing everything needed for a direct screw-in replacement. Licensed plumbers and water heater service technicians are the typical installers for this type of element.

This element is suited for residential storage-tank water heaters and light commercial water heating equipment that accept a standard screw-in element configuration. The Incoloy nickel-alloy sheathing makes it well matched to hard-water and high-mineral environments where standard copper-sheath elements experience accelerated corrosion or early failure. The included gasket simplifies the replacement process and helps ensure a leak-free installation.

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater service technician in accordance with local plumbing codes and the tank manufacturer's service documentation. Always shut off electrical power to the water heater at the breaker panel and close the cold-water supply valve before removing the existing element. Drain the tank sufficiently to expose the element port, then use an element socket wrench to remove and replace the element. Inspect the new gasket seating surface before torquing the element to ensure a leak-free seal.
