This fitting is used when extending or connecting valve stems that differ in point count, allowing for proper mechanical engagement between components. It serves as a precision adapter in valve assemblies where direct stem-to-stem coupling would otherwise be incompatible. HVAC technicians, plumbers, and mechanical contractors working on valve replacement or retrofit applications rely on this type of stem knockout to maintain correct drive engagement and avoid slippage during valve operation.\u003c\/p\u003e\n\u003cp\u003eThis extension stem knockout is suited for applications involving valve stems in HVAC, plumbing, or refrigeration systems where a 20-point to 19-point transition is required. It is typically installed during valve replacement or upgrade projects where the existing actuator or valve body has a differing stem point count from the new component being fitted. Both residential and light commercial service scenarios may call for this part.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdapts 20-point valve stem to 19-point connection for cross-compatible installations\u003c\/li\u003e\n  \u003cli\u003eExtension design allows for stem reach adjustment during valve coupling\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for tight mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eManufactured by TAPCO, a recognized supplier of valve and flow-control components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or adapter component for valve stem assemblies requiring a 20-point to 19-point extension knockout interface.

Shut off the relevant fluid or refrigerant supply and depressurize the system before disassembling any valve components. Verify point-count engagement before applying torque to avoid stem damage or stripping. Follow all applicable local mechanical codes and manufacturer guidelines for valve service procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Point Configuration\u003c\/strong\u003e: 20-point x 19-point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 040688916385\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TAPCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73089\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TAPCO","offers":[{"title":"Default Title","offer_id":51234000699698,"sku":"73089","price":17.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307612882.jpg?v=1780114550","url":"https:\/\/voomisupply.com\/products\/tapco-73089-extension-stem-knockout-20pt-x-19pt","provider":"Voomi Supply","version":"1.0","type":"link"}
