Fluidmaster fluidmaster-6106 Tank to Bowl Kit 3 Bolt

Product Description

The FLUIDMASTER fluidmaster-6106 is a tank-to-bowl gasket and hardware kit designed to seal and secure a toilet tank to the bowl on close-coupled toilet installations. The kit centers on a sponge rubber gasket sized for 2-inch flush valve openings, paired with three solid brass bolts measuring 5/16 inch in diameter by 2.75 inches in length. The brass construction resists rust and corrosion in the wet environment of a toilet tank. Stainless steel nuts and washers, along with plastic washers, are included so the installer has all hardware needed to complete the connection in a single service call.

This kit is suited for residential toilet service and repair work where the tank-to-bowl seal has failed or where a toilet is being reassembled after removal. It fits close-coupled toilets equipped with 2-inch flush valves and accommodates both round and hex-shaped flush valve nuts, making it a practical stock item for plumbers servicing a variety of toilet brands and configurations. The complete hardware package reduces callbacks caused by missing or corroded fasteners.

Key Features

• Sponge rubber gasket sized for 2-inch flush valve openings provides a reliable watertight seal
• Three solid brass bolts (5/16 inch by 2.75 inches) resist corrosion in constant-moisture environments
• Stainless steel washers and nuts included for a complete, corrosion-resistant fastener set
• Fits both round and hex-shaped flush valve nuts on close-coupled toilets
• Complete kit eliminates the need to source gasket and hardware separately

Compatibility

Designed for close-coupled toilets equipped with 2-inch flush valves. Accommodates round or hex-shaped flush valve nuts. Suitable as a universal replacement gasket and bolt kit for standard residential toilet tank-to-bowl connections.

Installation Notes

Installation is performed by a licensed plumber or qualified service technician. Shut off the water supply at the stop valve and flush the toilet to empty the tank before beginning disassembly. Hand-tighten the brass bolts evenly and alternate sides to seat the gasket uniformly, then snug with a wrench — avoid overtightening, which can crack the porcelain tank or bowl. Verify no leaks at the gasket and bolt penetrations after restoring water supply.
