The insert end expands into PEX-A pipe using an expansion tool, creating a reliable, compression-style seal when the pipe contracts around the fitting. The female sweat end accepts a standard copper male-sweat fitting or valve, allowing integration with existing copper systems. Licensed plumbers install this fitting in residential and light commercial potable water distribution systems where PEX-A and copper must be joined at a transition point.\u003c\/p\u003e\u003cp\u003eThis adapter is suited for cold and hot water supply lines in new construction and retrofit projects. It is commonly used where a PEX-A branch line meets a copper manifold, shutoff valve, or fixture connection. The lead-free brass construction meets requirements for potable water contact. The fitting is appropriate for concealed and exposed installations in walls, ceilings, and mechanical spaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLead-free brass construction rated for potable water service\u003c\/li\u003e\n\u003cli\u003ePEX-A insert end requires an expansion tool for installation, producing a strong mechanical connection\u003c\/li\u003e\n\u003cli\u003eFemale sweat end solders to standard copper male-sweat fittings and valves\u003c\/li\u003e\n\u003cli\u003e0.5-inch nominal size fits standard half-inch PEX-A tubing\u003c\/li\u003e\n\u003cli\u003eCompact design allows installation in tight spaces typical of residential rough-in work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style transition fitting for 0.5-inch PEX-A tubing systems connecting to female sweat copper fittings in residential and light commercial potable water applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of the PEX-A insert end requires a compatible PEX-A expansion tool and the appropriate expander head for 0.5-inch tubing. Shut off the water supply and depressurize the line before beginning work. The female sweat end should be soldered by a licensed plumber following applicable IPC and local plumbing code requirements, using lead-free solder on potable water systems. Allow solder joints to cool fully before restoring pressure to the line.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: PEX-A Insert x Female Sweat (Solder)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Lead-Free Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 811734021748\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrder Increment\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AY MCDONALD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5423-279\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AY MCDONALD","offers":[{"title":"Default Title","offer_id":51396436033842,"sku":"5423-279","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312834217.jpg?v=1782831929","url":"https:\/\/voomisupply.com\/products\/ay-mcdonald-5423-279-pex-a-brass-insert-female-sweat-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
