The suction and liquid lines are mechanically joined together, allowing faster routing and a cleaner installation compared to separate lines. This 50-foot set pairs a 1\/4-inch liquid line with a 1\/2-inch suction line and includes flare nuts. The closed-cell foam insulation is factory-applied and rated for high-pressure refrigerant service including R-410A systems. An outer white polyethylene jacket protects the insulation during pull-through and rough-in work. Licensed HVAC technicians and refrigeration mechanics are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis line set is suited for residential and light commercial applications where a factory-paired line set speeds up installation. Typical use cases include ductless mini-split wall or ceiling cassette installs, VRF branch runs, and replacement line sets on heat pump systems. The 50-foot length accommodates standard residential runs between the outdoor condenser and indoor air handler. Foot markings are printed incrementally on the insulation jacket, allowing technicians to measure accurately in the field, confirm initial refrigerant charge length, and reduce unnecessary copper waste during trimming.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSuction and liquid lines mechanically attached for faster, single-pull installation\u003c\/li\u003e\n  \u003cli\u003eUL723 Classified R39562 per ASTM E84 with a 25\/50 flame spread and smoke development rating\u003c\/li\u003e\n  \u003cli\u003eUL Performance Verified for UV resistance, tested for a minimum of 5 years of outdoor exposure\u003c\/li\u003e\n  \u003cli\u003eWhite polyethylene outer jacket guards foam insulation against tearing during installation\u003c\/li\u003e\n  \u003cli\u003eIncremental foot markings on insulation for accurate charge length measurement and reduced copper waste\u003c\/li\u003e\n  \u003cli\u003eRated for high-pressure refrigerant applications including R-410A service\u003c\/li\u003e\n  \u003cli\u003ePaintable insulation surface allows color matching to exterior walls or equipment enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSuitable for ductless mini-split, VRF, heat pump, and unitary systems requiring a 1\/4-inch liquid line and 1\/2-inch suction line configuration with high-pressure refrigerant compatibility.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or refrigeration mechanic in compliance with applicable mechanical codes. De-energize and recover refrigerant from any existing system before disconnecting or connecting line sets. Flare connections must be made with proper flaring tools to ensure leak-free joints; do not overtighten flare nuts. Protect the line set jacket from sharp edges during routing to maintain insulation integrity.\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: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant Compatibility\u003c\/strong\u003e: R-410A and other high-pressure refrigerants\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Jacket Material\u003c\/strong\u003e: White polyethylene\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\u003eFire Rating\u003c\/strong\u003e: UL723 Classified R39562, ASTM E84 25\/50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Hardware\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.lsin141212050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51383713399090,"sku":"FN.LSIN141212050","price":356.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674706.webp?v=1782605237","url":"https:\/\/voomisupply.com\/products\/parker-fn-lsin141212050-copper-line-set-50-ft-mini-split","provider":"Voomi Supply","version":"1.0","type":"link"}
