The set includes a 3\/4-inch OD suction line and a 3\/8-inch OD liquid line, both with factory-applied 3\/4-inch thick foam insulation. At 30 feet in length, it suits standard residential installations where the distance between the indoor air handler and outdoor condensing unit requires a pre-measured, ready-to-install run. Licensed HVAC technicians install this line set as part of new system commissioning or equipment changeouts.\u003c\/p\u003e\u003cp\u003eThis line set is suited for attic runs, wall penetrations, and outdoor routing where thicker insulation is needed to reduce condensation on the suction line and limit thermal gain on the liquid line. The 3\/4-inch insulation thickness exceeds the wall thickness found on standard line sets, making it a preferred choice in high-humidity climates or applications where the lines are exposed to elevated ambient temperatures. It is compatible with residential split-system air conditioners and heat pumps that use the matching line sizes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30-foot factory-measured length for straightforward residential system runs\u003c\/li\u003e\n\u003cli\u003e3\/4-inch OD suction line and 3\/8-inch OD liquid line match common residential split-system connections\u003c\/li\u003e\n\u003cli\u003e3\/4-inch thick factory-applied foam insulation controls condensation and reduces thermal loss\u003c\/li\u003e\n\u003cli\u003eCopper construction provides reliable refrigerant containment and long service life\u003c\/li\u003e\n\u003cli\u003ePre-insulated from the factory reduces field labor during installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation line set for residential split-system air conditioners and heat pumps requiring 3\/4-inch OD suction and 3\/8-inch OD liquid line connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician holding an EPA Section 608 certification for handling refrigerants. Shut down and recover any refrigerant from an existing system before disconnecting line sets. Connections are typically brazed using nitrogen purge per industry best practice to prevent oxidation inside the copper tubing. Avoid sharp bends that could kink the tubing and restrict refrigerant flow.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuction Line OD\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiquid Line OD\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Thickness\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLine Set Length\u003c\/strong\u003e: 30 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MUELLER STREAMLINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LS-343830P-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51347683803442,"sku":"LS-343830P-12","price":377.25,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552559.jpg?v=1782111268","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-ls-343830p-12-line-set-30-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
