It includes both the suction and liquid lines mechanically attached to each other, simplifying routing and reducing install time. The suction line measures 3\/8 inch, the liquid line measures 1\/4 inch, and the overall outer jacket diameter is 1\/2 inch. The set is 15 feet in length and comes with flare nuts pre-attached. Foam insulation is covered by a white polyethylene outer jacket that resists tearing during installation. HVAC technicians handling R-410A or other high-pressure refrigerant systems will find this line set sized and rated for those applications.\u003c\/p\u003e\n\u003cp\u003eThis line set is suited for residential and light commercial HVAC installations where a compact, ready-to-run refrigerant piping solution is required. It is rated for use with high-pressure refrigerants including R-410A. The 1\/4 inch by 3\/8 inch configuration matches the most common connection sizes found on ductless mini-split indoor and outdoor units. The 15-foot length covers typical short-run installations. Foot markings printed on the insulation allow technicians to track line length accurately during installation, which supports correct initial refrigerant charge calculations and minimizes copper waste.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSuction and liquid lines mechanically attached for faster, cleaner routing\u003c\/li\u003e\n  \u003cli\u003eUL723 Classified R39562 (ASTM E84 25\/50) foam insulation\u003c\/li\u003e\n  \u003cli\u003eWhite polyethylene outer jacket protects foam insulation from tearing during pull-through and bending\u003c\/li\u003e\n  \u003cli\u003eUV resistant insulation — UL Performance Verified for a minimum of 5 years UV exposure\u003c\/li\u003e\n  \u003cli\u003eFoot markings on insulation support accurate line-length measurement and initial charge calculation\u003c\/li\u003e\n  \u003cli\u003ePaintable outer surface allows insulation to be finished to match surrounding surfaces\u003c\/li\u003e\n  \u003cli\u003eCompatible with R-410A and other high-pressure refrigerant applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a preinsulated OEM-style refrigerant line set for ductless mini-split, VRF, heat pump, and unitary HVAC systems requiring a 1\/4 inch liquid line and 3\/8 inch suction line configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician holding an EPA Section 608 certification where refrigerant handling is involved. Power down and de-energize the system at the disconnect before connecting or disconnecting refrigerant lines. Use proper flare tooling to ensure leak-free connections at the flare nut fittings — do not overtighten flare nuts, as this can crack or distort the copper seat. Follow local mechanical codes and the equipment manufacturer's specifications for line set routing, support spacing, and evacuation procedures before charging the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Line Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuction Line Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Jacket Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 15 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Jacket Material\u003c\/strong\u003e: White polyethylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant Compatibility\u003c\/strong\u003e: R-410A and high-pressure refrigerant applications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUV Resistance\u003c\/strong\u003e: UL Performance Verified, minimum 5 years\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification\u003c\/strong\u003e: UL723 Classified R39562 (ASTM E84 25\/50)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Flare nuts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: fn.lsin143812015\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51383789945138,"sku":"FN.LSIN143812015","price":150.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674716.webp?v=1782607529","url":"https:\/\/voomisupply.com\/products\/parker-fn-lsin143812015-copper-line-set-15-ft-1-4-x-3-8-x-1-2","provider":"Voomi Supply","version":"1.0","type":"link"}
