The suction and liquid lines are mechanically joined together, reducing handling time and simplifying routing during installation. The liquid line measures 1\/4 inch, the suction line measures 5\/8 inch, and the insulation wall thickness is 1\/2 inch. Total line set length is 50 feet. Both lines ship ready to connect, with flare nuts included. This line set is rated for high-pressure refrigerants including R-410A and is UL723 Classified under ASTM E84 with a 25\/50 flame spread and smoke developed index rating.\u003c\/p\u003e\u003cp\u003eThis line set is suited for residential and light commercial applications where ductless mini-split, VRF, or heat pump systems are being installed or replaced. The 50-foot length covers most single-zone and multi-zone runs. The mechanically attached dual-line configuration keeps the suction and liquid lines aligned during installation, which is particularly useful in tight chases, overhead runs, or exterior wall routing where managing two separate lines would slow the job.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSuction and liquid lines mechanically joined for faster, single-pass routing\u003c\/li\u003e\n\u003cli\u003eUL723 Classified, ASTM E84 rated 25\/50 flame spread and smoke developed index\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\u003eWhite polyethylene outer jacket protects foam insulation from tearing during pull-through and installation\u003c\/li\u003e\n\u003cli\u003eFoot markings printed incrementally along insulation for accurate refrigerant charge measurement and reduced copper waste\u003c\/li\u003e\n\u003cli\u003eRated for high-pressure refrigerant applications including R-410A\u003c\/li\u003e\n\u003cli\u003ePaintable insulation jacket for aesthetic matching to surrounding surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ductless mini-split, VRF, heat pump, and unitary systems requiring a 1\/4-inch liquid line and 5\/8-inch suction line with 1\/2-inch insulation wall thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with refrigerant piping and local mechanical codes. Shut down and lock out the system before making any line connections. Flare fittings must be made with the correct flare tool for the line diameter — inspect all flares before pressurizing the system. Do not exceed the bend radius of the copper tubing, and support the line set at intervals consistent with applicable mechanical code requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 5\/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\u003eLine Set Length\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\u003eCertifications\u003c\/strong\u003e: UL723 Classified R39562, ASTM E84 25\/50, UL Performance Verified UV Resistance\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: Minimum 5 years verified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components\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: fn.lsin145812050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51383870947634,"sku":"FN.LSIN145812050","price":436.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674683.webp?v=1782610111","url":"https:\/\/voomisupply.com\/products\/parker-fn-lsin145812050-copper-line-set-50-ft-1-4x5-8x1-2","provider":"Voomi Supply","version":"1.0","type":"link"}
