The liquid line measures 1\/4 inch and the suction line measures 3\/8 inch, with both lines fully insulated using 3\/8-inch-wall elastomeric (black) insulation. Copper tubing is manufactured from C12200 alloy, meeting ASTM B1003 standards and rated to 700 psi per UL requirements. Licensed HVAC technicians install this line set when connecting a ductless mini split indoor air handler to its outdoor condensing unit.\u003c\/p\u003e\n\u003cp\u003eThis line set is suited for residential and light-commercial ductless mini split installations where a pre-configured flare-connection line set is required. Both lines arrive insulated, reducing field labor for insulation wrap. The 1\/4-inch liquid line and 3\/8-inch suction line diameters are common pairings for single-zone mini split systems. No 90-degree pre-formed bends are included, allowing the installer to route and bend the lines to fit the specific job layout.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eC12200 copper tubing meets ASTM B1003 and is UL-rated to 700 psi\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch liquid line and 3\/8-inch suction line — common mini split sizing\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch-wall elastomeric black insulation on both lines\u003c\/li\u003e\n  \u003cli\u003eFlare fittings factory-installed on both lines — no field flaring required at connection ends\u003c\/li\u003e\n  \u003cli\u003eStraight configuration with no pre-formed 90-degree bends for flexible routing\u003c\/li\u003e\n  \u003cli\u003eBoth lines insulated from the factory, reducing field wrap labor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation line set for ductless mini split systems requiring 1\/4-inch liquid and 3\/8-inch suction line connections with flare fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician following applicable mechanical codes and EPA Section 608 refrigerant handling requirements. Shut down and isolate the mini split system completely before connecting or disconnecting line set fittings. Verify flare seat condition and torque flare nuts to the mini split manufacturer's specification using calibrated flare-nut wrenches — do not over-tighten. Pressure-test and evacuate the line set to the system manufacturer's required vacuum level before introducing refrigerant.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLine Set Type\u003c\/strong\u003e: Mini Split Line Set\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Line Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuction Line Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Material\u003c\/strong\u003e: Elastomeric (black)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Wall Thickness\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Flare Fittings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoth Lines Insulated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e90-Degree Bends\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: C12200 Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM B1003, UL 700 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.21 pounds\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: MUELLER INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 40680150b3b6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER INDUSTRIES","offers":[{"title":"Default Title","offer_id":51268129063218,"sku":"40680150B3B6","price":156.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40620100B3B6.jpg?v=1780699802","url":"https:\/\/voomisupply.com\/products\/mueller-industries-40680150b3b6-mini-split-line-set","provider":"Voomi Supply","version":"1.0","type":"link"}
