Key Performance Features

• High-Grade Incoloy® Alloy: The element is constructed from Incoloy, a nickel-chromium alloy designed to resist high-temperature oxidation and "pitting" corrosion common in marine water systems.

• 1-1/4" BSP Thread: Features the standard British Standard Pipe (BSP) threading used across the Quick B3 and Sigmar product lines for a leak-free, high-pressure seal.

• Integrated Thermostat Pocket: Includes the internal sleeve (well) designed to hold the temperature sensing probe of the thermostat, ensuring accurate temperature control and safety shut-off.

• 110V Optimized: Specifically wound for 110-120V AC systems, common on North American vessels, providing efficient heat transfer without tripping breakers.

• OEM Compatibility: Guaranteed to fit Quick B3 series (rectangular and cylindrical) and Sigmar Marine Compact/Termoinox models.

Technical Specifications

In The Box

• 1 x 1200W Heating Element

• 1 x Rubber Sealing Gasket (O-ring)

Note: The thermostat (the plastic control box that plugs into the element) is usually sold separately. If your heater tripped the "high-limit" reset button and won't restart, you should inspect both the element and the thermostat.

Installation Safety Pro-Tips

1. POWER OFF: Always disconnect the AC breaker and ensure the water heater is powered down before attempting replacement.

2. Drain the Tank: You must drain the water heater below the level of the element before removal to avoid flooding your engine room or locker.

3. The "Dry-Fire" Rule: Once the new element is installed, fill the tank completely and open a hot water faucet until all air is bled from the lines before turning the power back on. Turning the power on to a dry tank will destroy the new element in seconds.

4. Scaling Prevention: If your old element was covered in white crust (calcium), consider installing a water softener or flushing your tank annually to extend the life of the new element.
