This fitting allows a licensed plumber to bridge PEX-A flexible pipe runs to copper sweat fittings without additional adapters or specialty tools beyond standard PEX expansion and sweat equipment. The lead-free brass construction meets potable water requirements, making it appropriate for domestic water supply systems in residential and light commercial applications. Its insert-style end grips the interior of the PEX-A tube after expansion, creating a reliable, watertight mechanical connection.\u003c\/p\u003e\u003cp\u003eThis adapter is used where PEX-A distribution lines must terminate at or connect to copper sweat assemblies. Common install scenarios include mixing manifold transitions, water heater connections, fixture supply rough-ins, and retrofit work where existing copper lines are being extended with PEX-A. The 1-inch size suits main distribution runs in residential systems and branch mains in small commercial builds. It is intended for use with PEX-A tubing only, not PEX-B or PEX-C, as the expansion method is specific to PEX-A material memory properties.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLead-free brass construction meets NSF and Safe Drinking Water Act requirements for potable water contact\u003c\/li\u003e\n\u003cli\u003eInsert end designed for use with PEX-A expansion tooling for a secure, memory-fit connection\u003c\/li\u003e\n\u003cli\u003eMale sweat end solders to standard copper fittings using conventional torch and solder method\u003c\/li\u003e\n\u003cli\u003e1-inch size fits main distribution and branch main applications\u003c\/li\u003e\n\u003cli\u003eSingle-unit order increment allows purchase of exact quantities needed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style transition fitting for 1-inch PEX-A tubing systems connecting to copper sweat piping assemblies in residential and light commercial potable water applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize the line before beginning work. Use a calibrated PEX-A expansion tool sized for 1-inch tubing to expand the PEX-A end before seating the insert; allow the tubing to recover fully around the fitting. Complete all sweat soldering on the copper end before connecting to the PEX-A side to avoid heat damage to the tubing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: PEX-A Insert x Male Sweat\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: 811734024633\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: 5423-276\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AY MCDONALD","offers":[{"title":"Default Title","offer_id":51396277338418,"sku":"5423-276","price":21.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312834202.jpg?v=1782828890","url":"https:\/\/voomisupply.com\/products\/ay-mcdonald-5423-276-pex-a-brass-insert-sweat-adapter-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
