Fluval Bulb & Gasket for FX UVC In-Line Clarifier – Genuine Replacement Parts for Reliable UV Filtration

The Fluval Bulb & Gasket Set is the official replacement kit for the Fluval FX UVC In-Line Clarifier. Designed to restore your system’s sterilization efficiency, this kit includes a 6W ultraviolet bulb and matching gasket for a perfect, leak-proof fit.
