It ships as a 50-foot roll consisting of two copper tubes — 3\/8 inch and 5\/8 inch — each wrapped in 1\/2 inch thick polyethylene foam insulation. The copper tubing meets ASTM B280 standards for ACR service, and the insulation carries UL Verification with a 3-year anti-UV rating and an R-Value of 4.0. Flare nuts are included. Compatible with high-pressure refrigerants including R-410A. HVAC technicians install this line set during new equipment installations and system replacements.\u003c\/p\u003e\u003cp\u003eThis line set is suited for residential and light commercial air conditioning applications including unitary split systems, ductless mini-split systems, variable refrigerant flow (VRF) systems, and heat pumps. The 50-foot length covers most standard residential runs. Each roll is marked by the foot, which supports accurate refrigerant charging calculations and helps minimize material waste on the job. The paintable insulation surface allows finished installations to blend with exterior surfaces without additional covering.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eASTM B280 copper tubing rated for ACR refrigerant service\u003c\/li\u003e\n\u003cli\u003eUL Certified insulation with 3-year anti-UV polyethylene foam, R-Value 4.0\u003c\/li\u003e\n\u003cli\u003eCompatible with high-pressure refrigerants including R-410A\u003c\/li\u003e\n\u003cli\u003eFoot markings on each roll for accurate charge calculations and waste reduction\u003c\/li\u003e\n\u003cli\u003ePaintable insulation surface for finished exterior installations\u003c\/li\u003e\n\u003cli\u003eFlare nuts included — no separate fittings required for standard connections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eSuitable for all air conditioning applications including unitary split systems, ductless mini-splits, VRF systems, and heat pumps using high-pressure refrigerants such as R-410A.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with applicable mechanical codes and refrigerant handling regulations. Disconnect and lock out power to all equipment before making line set connections. Flare connections must be inspected for proper seating and leak-checked after startup. Avoid kinking the tubing during uncoiling — use a line set straightener or unroll carefully to maintain tube integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Thickness\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Material\u003c\/strong\u003e: Polyethylene foam (anti-UV)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation R-Value\u003c\/strong\u003e: 4.0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTubing Standard\u003c\/strong\u003e: ASTM B280\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Certification\u003c\/strong\u003e: UL Verified, 3-year anti-UV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefrigerant Compatibility\u003c\/strong\u003e: High-pressure refrigerants including R-410A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFittings Included\u003c\/strong\u003e: Flare nuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: tg.lsin385812050-fn\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51383099851058,"sku":"TG.LSIN385812050-FN","price":500.85,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674582.webp?v=1782588130","url":"https:\/\/voomisupply.com\/products\/parker-tg-lsin385812050-fn-preinsulated-copper-line-set-50ft","provider":"Voomi Supply","version":"1.0","type":"link"}
