{"product_id":"brasscraft-st3546b-diverter-stem","title":"Brasscraft ST3546B Diverter Stem","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe BRASSCRAFT ST3546B is a replacement diverter stem designed for faucet and shower valve service. The diverter stem controls flow direction within the valve body, redirecting water between outlets such as a tub spout and showerhead. This part cross-references to American Standard application 9803-02 and is installed by licensed plumbers or experienced pipe tradespeople during valve repair or rebuild service. It is a direct OEM-style replacement intended to restore proper diverter function without replacing the entire valve assembly.\u003c\/p\u003e\u003cp\u003eThe ST3546B is suited for residential faucet and shower diverter valve repair. It fits into the valve body in place of a worn or failed original stem, making it appropriate for tub and shower combination fixtures where diverter function has degraded. Technicians typically source this stem when rebuilding a valve that is leaking, failing to divert, or passing water to both outlets simultaneously.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOEM-style replacement diverter stem for faucet and shower valve service\u003c\/li\u003e\n\u003cli\u003eCross-references to American Standard 9803-02 application\u003c\/li\u003e\n\u003cli\u003eRestores proper flow-direction control within the valve body\u003c\/li\u003e\n\u003cli\u003eSupports rebuild service without full valve replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement diverter stem cross-referencing American Standard application 9803-02.
