Ao Smith 100110131 Flanged Incoloy Element 9KW 480/277V

Product Description

The AO SMITH 100110131 is a flanged Incoloy heating element designed for commercial electric water heaters. Rated at 9 kilowatts and compatible with 480/277-volt supply, it features an Incoloy nickel-alloy sheath that resists corrosion and scale buildup in demanding water conditions. Medium watt density reduces surface temperature at the sheath, extending service life in hard-water applications. The element ships with a gasket included and mounts to both round and square flange patterns on a 2.5-inch bolt circle. Strong, forged steel flanges provide a durable, leak-resistant seal. Licensed commercial plumbers and HVAC technicians install this element as a direct OEM-style replacement during routine maintenance or emergency service calls.

This element is used in commercial electric water heater installations where high-voltage, high-capacity heating is required. It is rated for use in commercial environments and fits AO SMITH DSE Series, CMC Series, SU Series, and DVE/DHE Series water heaters. The 2.5-inch bolt-circle flange mount accommodates both round and square flange configurations, making it a versatile fit across multiple commercial tank designs. The included gasket eliminates the need to source a separate seal, reducing parts procurement time on the job.
