American Standard 989201 Cap and Plunger Assembly

Product Description

The American Standard 989201 is a cap and plunger assembly designed as a replacement component for plumbing fixture or valve applications. This assembly combines a cap and plunger into a single serviceable unit, restoring proper function to the valve or fitting it supports. Licensed plumbers and experienced service technicians install this type of component during routine maintenance or when a worn or damaged assembly causes leaking, poor seating, or loss of flow control. The packaged format includes all necessary parts for a complete swap-out without sourcing components separately.

This cap and plunger assembly is suited for use in residential and light commercial plumbing systems where American Standard components are specified. It is a direct OEM-style replacement intended to restore original performance characteristics to the serviced fixture or valve. Installations typically occur during scheduled maintenance or in response to a confirmed failure of the existing cap or plunger.
