It transitions between crimp-style PEX connections and standard fitting ends, allowing technicians to integrate PEX tubing runs with threaded or push-fit components in a single fitting. Constructed from domestic brass, this adapter delivers reliable corrosion resistance and is suited for potable water and hydronic distribution applications. Licensed plumbers and pipefitters install this fitting as part of residential and light commercial PEX installations where a secure, leak-free crimp connection is required.\u003c\/p\u003e\n\u003cp\u003eThis adapter is used in 3\/4-inch PureFlow PEX plumbing systems, including domestic hot and cold water distribution, radiant heating supply and return lines, and manifold branch connections. The crimp end accepts a standard crimp ring compressed with a PEX crimp tool, while the fitting end connects to compatible downstream components. It is appropriate for both new construction rough-in and retrofit applications where existing piping is being converted to or extended with PEX.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch nominal size for standard PureFlow PEX plumbing runs\u003c\/li\u003e\n  \u003cli\u003eCrimp x fitting end style for versatile connection transitions\u003c\/li\u003e\n  \u003cli\u003eDomestic brass construction for corrosion resistance in potable water service\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard PEX crimp rings and crimp tools\u003c\/li\u003e\n  \u003cli\u003eSuitable for both hot and cold water distribution and hydronic systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for 3\/4-inch VIEGA PureFlow PEX crimp plumbing systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and ASTM F1807 crimp connection standards. Shut off the water supply and depressurize the line before cutting into existing piping. Use a properly calibrated PEX crimp tool sized for 3\/4-inch crimp rings to ensure a leak-free connection. Do not over-compress the crimp ring or substitute non-rated ring materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Crimp x Fitting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\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: VIEGA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 46644\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VIEGA","offers":[{"title":"Default Title","offer_id":51524755751218,"sku":"VPEX46644","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84d34fff5288e3cb8155c7a297bec9be.jpg?v=1785456949","url":"https:\/\/voomisupply.com\/products\/viega-46644-pureflow-crimp-adapter-3-4-inch-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
