Lavelle Industries Inc 464BP Tank to Bowl Gasket Kit

Product Description

The LAVELLE INDUSTRIES INC 464BP is a tank-to-bowl gasket hardware kit designed for two-piece toilet installations. The kit centers on a sponge rubber gasket that seals the connection between the toilet tank and bowl, preventing leaks at one of the most common failure points in residential and light commercial plumbing fixtures. The gasket measures 2-1/8 inches inner diameter by 3-1/2 inches outer diameter by 1-1/4 inches thick. Included hardware is stainless steel for corrosion resistance. Licensed plumbers and experienced DIYers install this kit during toilet repairs or full toilet replacements.

This kit is intended for standard two-piece toilet tanks with a 2-inch flush valve outlet. The universal sponge rubber design is sized to fit most residential two-piece toilet tanks, making it a practical stock item for plumbing service trucks and supply rooms. It suits both repair and new-installation scenarios where the existing gasket has deteriorated, compressed, or begun to leak.

Key Features

Compatibility

Installation Notes

A licensed plumber or qualified tradesperson should shut off the water supply at the stop valve and flush the tank fully before removing the existing hardware. Drain residual water from the tank before loosening tank bolts to avoid spills. Hand-tighten tank bolts evenly and snug with a wrench, alternating sides to seat the gasket uniformly — do not overtighten, as cracking the porcelain tank is a common result of excessive torque. Follow IPC and local plumbing code requirements for toilet fixture connections.
