It includes both a 1\/4 inch liquid line and a 3\/8 inch suction line, each insulated with 1\/2 inch wall insulation to minimize heat gain and condensation along the refrigerant circuit. The tubing is plain end, meaning field flaring is required at both connections. At 50 feet in length, this lineset suits installations where the indoor air handler is mounted at a moderate distance from the outdoor condensing unit. HVAC technicians working on residential or light commercial ductless systems will find this a direct-use component requiring no additional insulation materials for a standard run.\u003c\/p\u003e\u003cp\u003eThis lineset is used in ductless mini split system installations where the indoor evaporator unit and outdoor condensing unit require a refrigerant circuit connection. The 50-foot length accommodates wall penetrations, vertical drops, and horizontal runs common in residential installations. Plain end tubing requires the technician to flare each line end on site to match the service port fittings on both the indoor and outdoor units. Both lines arrive fully insulated, reducing field labor associated with sleeving individual copper lines after routing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4 inch liquid line and 3\/8 inch suction line sized for standard mini split systems\u003c\/li\u003e\n\u003cli\u003e1\/2 inch wall insulation on both lines reduces heat transfer and condensation\u003c\/li\u003e\n\u003cli\u003ePlain end tubing allows field flaring for direct connection to indoor and outdoor units\u003c\/li\u003e\n\u003cli\u003e50-foot length suits moderate-distance residential and light commercial runs\u003c\/li\u003e\n\u003cli\u003eBoth lines insulated from the factory, reducing on-site insulation labor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation lineset for residential and light commercial ductless mini split systems requiring a 1\/4 inch liquid line and 3\/8 inch suction line configuration.\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, as this work involves a sealed refrigerant circuit. Power down the entire mini split system at the disconnect before making any connections. Use a proper flaring tool to create leak-free flare connections at both the indoor and outdoor unit ports, and pressure-test the line set before evacuating and charging the system. Avoid sharp bends in the copper tubing that could restrict refrigerant flow or crack the insulation jacket.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiquid Line Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuction Line Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Wall Thickness\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLineset Length\u003c\/strong\u003e: 50 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Plain End (field flare required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Coverage\u003c\/strong\u003e: Both lines insulated\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CERRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 406-2-50\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CERRO","offers":[{"title":"Default Title","offer_id":51268369547570,"sku":"406-2-50","price":333.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913055.jpg?v=1780703381","url":"https:\/\/voomisupply.com\/products\/cerro-406-2-50-mini-split-lineset-1-4x3-8-50-ft-insulated","provider":"Voomi Supply","version":"1.0","type":"link"}
