Plumb Shop Div Brasscraft 818-986 Flush Valve Seal

Product Description

The PLUMB SHOP DIV BRASSCRAFT 818-986 is a rubber flush valve seal designed as a direct replacement for Mansfield 210 New Style flush valves. This seal forms the critical watertight interface between the flush valve and the tank outlet, preventing leaks and ensuring a consistent, complete flush cycle. Made from rubber, it resists the continuous water exposure common in toilet tank environments. Licensed plumbers and experienced DIYers install this part during routine toilet repairs or when a running toilet indicates a worn or degraded flush valve seal.

This flush valve seal is intended for residential toilet repair applications where a Mansfield 210 New Style flush valve is installed. It is a carded, single-unit replacement part suited for service calls, maintenance stock, or owner-performed repairs. The compact package dimensions of 6.2 inches by 4.06 inches by 4.89 inches make it easy to carry on a service truck or store in a parts kit.

Installation Notes

Installation is typically performed by a licensed plumber or a knowledgeable DIYer familiar with toilet tank components. Shut off the water supply valve at the base of the toilet and flush to drain the tank before beginning work. Remove the old seal carefully to avoid disturbing surrounding valve components. Follow local plumbing codes, such as those referenced in the IPC, for any toilet repair work.
