Tapco 057 KO-3S Left Hand Stem

Product Description

The TAPCO 057 is a left-hand stem designed as a replacement valve component for plumbing and fluid control systems. Stems serve as the core operating part of a valve, translating handle or actuator movement into the opening or closing of the valve seat. Left-hand stems are orientation-specific and must be matched correctly to the valve body during service or repair. This part is intended for installation by licensed plumbers and pipefitters performing valve repair or replacement work.

The TAPCO 057 KO-3S left-hand stem is suited for valve maintenance applications where the original stem has worn, corroded, or failed. It is used in residential and light commercial plumbing systems during valve rebuild or service procedures. Installers should verify stem orientation and valve model compatibility before ordering to ensure proper fitment.

• Left-hand stem orientation for correct directional valve operation
