It consists of two copper lines enclosed in insulation — a 3\/8-inch suction line and a 7\/8-inch liquid line — spanning 20 feet in length. This configuration handles the refrigerant transfer between an outdoor condensing unit and an indoor evaporator coil. HVAC technicians use linesets like this to reduce field fabrication time and ensure consistent insulation coverage along the full run. The standard-grade insulation helps limit heat gain on the suction line and maintains system efficiency during normal operation.\u003c\/p\u003e\n\u003cp\u003eThis lineset suits standard split-system air conditioning and heat pump installations in residential construction and light commercial applications. It is appropriate for single-story and two-story homes where a 20-foot lineset run is sufficient to connect the outdoor unit to the indoor air handler. The 3\/8-inch by 7\/8-inch diameter pairing is a common size for equipment in the 2-ton to 4-ton capacity range. Licensed HVAC technicians typically install this product as part of a new system installation or as a replacement for a damaged or undersized lineset.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePre-insulated copper construction reduces field fabrication and speeds installation\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch suction line and 7\/8-inch liquid line in a single 20-foot assembly\u003c\/li\u003e\n  \u003cli\u003eStandard insulation jacket limits heat transfer along the suction line\u003c\/li\u003e\n  \u003cli\u003eCompatible diameter pairing commonly used with 2-ton to 4-ton split systems\u003c\/li\u003e\n  \u003cli\u003e20-foot length suits a wide range of single-family residential installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install lineset for residential split-system air conditioners and heat pumps requiring a 3\/8-inch by 7\/8-inch lineset configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with local mechanical codes and manufacturer guidelines. Before connecting the lineset, shut down and lock out the outdoor unit and indoor air handler completely. Flare or braze connections should be made with proper tooling; all brazed joints must be made with nitrogen flowing through the lines to prevent oxidation scale inside the copper. Inspect the insulation for gaps or compression after routing, and seal any exposed sections before system startup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuction Line Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Line Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 20 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper with insulation jacket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 75865935634\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: CAMBRIDGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 312736\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CAMBRIDGE","offers":[{"title":"Default Title","offer_id":51468660736306,"sku":"312736","price":209.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/LSBlineset.jpg?v=1783920035","url":"https:\/\/voomisupply.com\/products\/cambridge-312736-copper-lineset-3-8x7-8-20ft-hvac","provider":"Voomi Supply","version":"1.0","type":"link"}
