Fluidmaster Inc 6102 Tank to Bowl Bolt Gasket Kit

Product Description

The FLUIDMASTER INC 6102 is a two-bolt tank-to-bowl kit designed to secure a toilet tank to its bowl while providing a watertight seal at the tank base. The kit includes two 5/16-inch by 3-inch brass bolts, a red sponge rubber tank-to-bowl gasket, four brass washers, four rubber washers, and two hex wing nuts. The gasket is engineered to fit over both round and hex-shaped flush valve nuts, making it a versatile choice for a wide range of toilet configurations. Plumbers and plumbing contractors rely on this kit for new installations and leak repairs on residential and light commercial toilets.

This kit is used during toilet installation or when replacing worn, cracked, or leaking tank hardware. It is appropriate for residential bathrooms, commercial restrooms, and rental property maintenance applications. The brass bolt construction resists corrosion in wet environments, and the sponge rubber gasket compresses to form a reliable seal between the tank and bowl. This kit is commonly installed when reseating a toilet tank, replacing corroded bolts, or addressing seepage at the tank-to-bowl connection.

Key Features

• Includes two 5/16-inch by 3-inch brass bolts for corrosion-resistant fastening
• Red sponge rubber gasket fits over both round and hex-shaped flush valve nuts
• Four brass washers and four rubber washers included for a complete hardware set
• Two hex wing nuts allow for hand-tightening during initial alignment
• Complete kit eliminates the need to source individual components separately

Compatibility

Designed as an OEM-style replacement tank-to-bowl hardware kit for residential and light commercial two-piece toilets with standard 5/16-inch bolt configurations.

Installation Notes

Installation should be performed by a licensed plumber or qualified tradesperson in accordance with local IPC requirements. Shut off the water supply and flush the tank to empty it before beginning work. Tighten wing nuts by hand first to align the tank, then snug bolts evenly with a wrench, alternating sides to avoid cracking the porcelain. Do not overtighten; porcelain tanks can crack under excessive fastener torque.
