The Fluidmaster B1T09CS is a 9-inch toilet connector that links your toilet tank fill valve to the water supply line. This braided stainless steel connector features a polymer core and Click Seal technology that audibly clicks when the connection reaches proper tightness, preventing over-tightening that can crack the connector nut and fill valve shank.
This flexible, kink-resistant model is designed for installation without tools or special equipment, making it convenient for both professional plumbers and homeowners performing their own repairs. The Click Seal end requires no wrenches or pliers—simply hand-tighten until you hear the click, which signals a proper seal and minimizes cross-threading and stripping for a leak-free fit.
Features and Benefits
- Click Seal Technology: The Click Seal nut clicks when the connector has reached proper seal, preventing over-tightening and cracking of the connector nut and fill valve shank.
- Braided Stainless Steel Construction: Durable stainless steel braiding over a polymer core resists kinking and creasing, even in tight spaces behind or beneath toilet tanks.
- Tool-Free Installation: No wrenches, pliers, or special tools required—simply hand-tighten the Click Seal end for fast installation.
- Minimizes Threading Errors: The Click Seal design minimizes cross-threading and stripping for a leak-free fit.
- Flexible and Maneuverable: The 9-inch length and flexible construction make routing around obstacles and into tight spaces simple during installation or replacement.
