Water Heater Heating Element 240V 5500W 1 in Screw-In NPSM Thread McMaster-Carr 35555K33
Replacement screw-in heating element for electric water heaters rated 240V AC and 5500W. This McMaster-Carr element uses a 1 in male NPSM thread and is commonly used where a standard 12 in element length fits the tank opening and internal clearance.
What this product is for
This replacement heating element is used to restore heating in compatible electric water heaters. It is a screw-in style element rated 240V AC and 5500W for residential and light commercial service applications where the heater is designed for this wattage and thread type.
Use for
Use for replacing a failed or scaled water heater element in a compatible tank-type electric water heater. Match the voltage, wattage, thread type, and element length before ordering.
Avoid for
Avoid using this element where the water heater requires a different wattage, voltage, fold-back shape, or flange style. Do not install in a tank that does not accept a 1 in screw-in male NPSM element.
Best for
Best for maintenance replacement on standard electric water heaters using a 240V, 5500W screw-in element. Suitable for buyers who need to match an existing straight element with approximately 12 in overall length and 9-1/2 in heated length.
Installed in
Installed in compatible electric storage water heaters in houses, apartment buildings, shops, and light commercial buildings. Typical 5500W elements draw about 22.9A at 240V, so they are commonly paired with a 30A branch circuit using #10 AWG copper conductors, subject to equipment nameplate and local electrical code.
Why this product exists
Water heater elements wear out from scale buildup, dry firing, or age. Replacing the element can restore hot water output without replacing the entire heater when the tank and controls are still serviceable.
Compared with similar products
This model is a standard screw-in water heater element rather than a thermostat, anode rod, or gasket-only service part. Compared with lower wattage elements, a 5500W element typically supports faster recovery in heaters designed for that load. Actual recovery depends on tank size, incoming water temperature, and heater design.
Guidance only: actual performance depends on installation conditions, water quality, insulation, layout, and local electrical code.
