It consists of a 3\/8-inch liquid line and a 1-1\/8-inch suction line, both running 30 feet in length with plain-end connections on each side. The suction line is wrapped in 1\/2-inch thick insulation to limit heat gain and maintain system efficiency. HVAC technicians use this line set to connect an outdoor condensing unit to an indoor evaporator coil or air handler, completing the refrigerant circuit between the two units.\u003c\/p\u003e\n\u003cp\u003eThis line set is suited for residential and light commercial split-system HVAC installations where a 30-foot run is needed between the indoor and outdoor equipment. The plain-end connections allow the installer to braze the line set directly to the service valves on the condensing unit and the distributor or expansion device on the indoor coil. The 3\/8-inch liquid line and 1-1\/8-inch suction line sizing is typical for larger-capacity residential or light commercial systems. Always verify that line set sizing matches the equipment manufacturer's specification for the unit being installed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e30-foot length suits most standard residential split-system runs\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch liquid line paired with 1-1\/8-inch suction line in a single assembly\u003c\/li\u003e\n  \u003cli\u003ePlain-end connections on both ends for field brazing\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch thick insulation on the suction line reduces heat gain and condensation\u003c\/li\u003e\n  \u003cli\u003ePre-paired construction simplifies pull-through and routing during installation\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 split-system air conditioners and heat pumps requiring a 3\/8-inch liquid line and 1-1\/8-inch suction line configuration. Always confirm line set sizing against the equipment manufacturer's published specifications before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician certified to handle refrigerants under EPA Section 608 regulations. Before connecting or disconnecting any refrigerant lines, recover all refrigerant from the system using certified recovery equipment and ensure both service valves are closed. Connections are plain-end and require brazing with nitrogen flowing through the lines to prevent oxidation scale inside the copper tubing. After installation, pressure-test and evacuate the line set to the equipment manufacturer's specified micron level before introducing refrigerant.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Line Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuction Line Diameter\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 30 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Thickness\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Plain End x Plain End\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: JMF COMPANY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 618_3\/8X1-1\/8X1\/2X30FT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JMF COMPANY","offers":[{"title":"Default Title","offer_id":51284037992754,"sku":"618_3\/8X1-1\/8X1\/2X30FT","price":365.51,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278384.jpg?v=1781066845","url":"https:\/\/voomisupply.com\/products\/jmf-company-618_3-8x1-1-8x1-2x30ft-line-set-30-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
