The set includes a 1\/4-inch liquid line and a 3\/8-inch suction line mechanically bonded together in a single assembly, spanning 50 feet in length, with flare nuts included. The suction line is insulated to a 1\/2-inch wall thickness. The dual-line construction reduces layout time and keeps refrigerant lines organized during rough-in. Licensed HVAC technicians installing split-system equipment are the primary users of this product.\u003c\/p\u003e\n\u003cp\u003eThis line set is suited for residential and light commercial applications where ductless mini-splits, heat pumps, VRF systems, or other unitary equipment require a pre-paired refrigerant piping solution. The mechanically attached suction and liquid lines simplify routing through walls, attics, and chases. The line set is compatible with R-410A and other high-pressure refrigerant systems. Foot markings printed on the insulation allow technicians to track length accurately during installation, supporting correct initial refrigerant charge calculations and minimizing copper waste.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSuction and liquid lines mechanically joined for faster, cleaner installation\u003c\/li\u003e\n  \u003cli\u003eUL723 Classified R39562 (ASTM E84 25\/50) flame and smoke rating\u003c\/li\u003e\n  \u003cli\u003eWhite polyethylene outer jacket protects foam insulation from tearing during pull-through\u003c\/li\u003e\n  \u003cli\u003eUL Performance Verified for UV resistance, tested for a minimum of 5 years of UV exposure\u003c\/li\u003e\n  \u003cli\u003eRated for use with R-410A and other high-pressure refrigerant gases\u003c\/li\u003e\n  \u003cli\u003eFoot markings on insulation for accurate length tracking and charge management\u003c\/li\u003e\n  \u003cli\u003ePaintable insulation surface allows color-matching to building exteriors or interior finishes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ductless mini-split, VRF, heat pump, and unitary HVAC systems requiring a 1\/4-inch liquid line and 3\/8-inch suction line configuration with R-410A or other high-pressure refrigerants.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with refrigerant piping and applicable mechanical codes. Recover and isolate refrigerant from any active system before making line set connections. Flare nuts are included; use a calibrated flaring tool and inspect each flare for cracks or deformation before torquing fittings. Do not bend the line set below its minimum bend radius, and avoid kinking the copper tubing during routing.\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\u003eInsulation Wall Thickness\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 high-pressure refrigerant applications\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\u003eFlame and Smoke 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.lsin143812050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51383813407026,"sku":"FN.LSIN143812050","price":336.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674703.webp?v=1782608136","url":"https:\/\/voomisupply.com\/products\/parker-fn-lsin143812050-twingel-line-set-50-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
