Eastman 40053 Plastic Flush Valve for Toilet Tanks

Eastman 40053 Plastic Flush Valve for Toilet Tanks

The Eastman 40053 is a plastic flush valve built for use inside a toilet tank, where it serves as the core component that releases water from the tank into the bowl during a flush cycle. Eastman supplies this flush valve as a replacement part for plumbers and contractors handling toilet tank repairs and rough-in service work, giving service techs a straightforward part to keep tank internals functioning correctly without pulling and replacing an entire tank assembly. As with other tank-trim components, this is a behind-the-fixture part intended for installation inside the tank, not a decorative or finish-grade item.

Key Features

• Plastic Construction: molded plastic body resists the corrosive effects of standing tank water better than unprotected metal components, making it a practical choice for wet, in-tank service.
• Flush Valve Function: mounts at the base of the toilet tank and opens to release the tank's stored water into the bowl on each flush cycle, then reseals to allow the tank to refill.
• Replacement-Part Design: sized and configured as a service replacement for existing toilet tank flush valve assemblies, allowing techs to restore tank operation without a full fixture swap.
• Eastman Sourcing: supplied under the Eastman brand, a name plumbing contractors and supply houses regularly stock for rough-in and repair parts.
