Therm 4.0kW Universal Flo Thru Element [9.9"] [240V] (25-4041-BI-TI)

Therm 4.0kW Universal Flo Thru Element [9.9"] [240V] (25-4041-BI-TI) is a heater service component for pool, spa, hot tub, or bath equipment repairs where the correct replacement part matters. This item is listed under Therm Products and is intended for the Heater Parts category, making it easier to match the part to the style of component being serviced. Use it when the existing part is cracked, worn, leaking, missing, corroded, discolored, stripped, electrically unreliable, or no longer performing as intended.

Before ordering, compare the product name, brand, category, and all identifying details with the part currently installed. Key fitment information includes listed details such as 9.9", 240V; measurements or ratings including 4.0kW, 240V; part number 25-4041-BI-TI. This is especially important on older spa and pool systems, where similar-looking Waterway, Hydro-Quip, Therm, Gecko, Raypak, Pentair, or other replacement parts may use different connection sizes, plug styles, face profiles, ratings, colors, or mounting configurations. Confirm the part number 25-4041-BI-TI, dimensions, voltage or flow requirements when applicable, and installation orientation before completing the repair.

This replacement is best used for heater repair or rebuild work where voltage, wattage, sensor location, element style, and matching dimensions need to be verified before installation. Replacing the correct component helps maintain dependable system performance, reduce downtime, and avoid unnecessary equipment damage caused by poor sealing, restricted flow, loose electrical connections, or mismatched plumbing. For best results, inspect adjacent gaskets, unions, fasteners, cords, sensors, or housings during installation and replace any worn supporting parts at the same time.
