Ensure your vacuum operates safely and efficiently with the Mengfan Replacement Water Pan Latches. This convenient 2-pack contains durable latches engineered to be exact replacements for the original part **R6178**, and they are fully compatible with models that use the interchangeable parts R6178, R2622, R4228, R3833.The water pan latch is a critical, though small, component of your cleaning system. It securely fastens the water pan to the main unit, creating a proper seal necessary for powerful vacuum suction.

Installing them is a straightforward DIY task that takes just moments, saving you time and money on professional repairs.Ideal for owners of D3, D4, and SE series vacuums, this 2-pack offers excellent value—install one now and keep the second as a handy spare for the future. Always verify the part number on your original latch to confirm compatibility. Maintain the integrity and performance of your premium cleaning system with Mengfan replacement parts.
