It includes a 3\/8-inch OD liquid line and a 3\/4-inch OD suction line, both manufactured from Cu29BA patent-pending anticorrosion copper that resists formicary and pitting corrosion. The suction line features 1\/2-inch polyethylene foam insulation with an additional white polyethylene outer jacket to protect the foam during installation. Foot markings are printed on the insulation at every foot to aid accurate initial refrigerant charging and minimize copper waste. Licensed HVAC technicians install this line set as part of a split-system refrigerant circuit.\u003c\/p\u003e\u003cp\u003eThis line set is rated for use with R-410A and other high-pressure refrigerant applications. The black insulation finish is paintable, allowing the line set to blend with exterior surfaces or building finishes. It is suited for residential and light commercial split-system installations where a factory-measured, pre-insulated line set simplifies the refrigerant circuit run between the indoor air handler and the outdoor condensing unit. The domestic origin and UL listing support code-compliant installations across most jurisdictions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCu29BA patent-pending copper construction resists formicary and pitting corrosion\u003c\/li\u003e\n\u003cli\u003e1\/2-inch polyethylene foam insulation with protective outer polyethylene jacket prevents damage during installation\u003c\/li\u003e\n\u003cli\u003eFoot markings printed every foot along insulation for accurate initial refrigerant charging\u003c\/li\u003e\n\u003cli\u003eCompatible with R-410A and other high-pressure refrigerant systems\u003c\/li\u003e\n\u003cli\u003eBlack insulation is paintable to match surrounding surfaces\u003c\/li\u003e\n\u003cli\u003eUL Listed and compliant with multiple ASTM standards including ASTM B-280 and ASTM C-1427-07\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation line set for residential and light commercial split-system air conditioning and heat pump systems 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 local mechanical codes and the system manufacturer guidelines. Recover all refrigerant and shut down system power before disconnecting or replacing any existing line set. Avoid kinking the copper lines during routing, and support the line set at regular intervals per applicable code requirements. Use the foot markings on the insulation to confirm line length and minimize excess copper before brazing connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiquid Line OD\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuction Line OD\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 40 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Thickness\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLine Set Type\u003c\/strong\u003e: Suction Line and Liquid Line\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper, Polyethylene Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefrigerant Compatibility\u003c\/strong\u003e: R-410A and high-pressure refrigerants\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eASTM Standards\u003c\/strong\u003e: ASTM B-1003, ASTM B-280, ASTM C-1427-07, ASTM E-84 25-50, ASTM E-96-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUL Listed\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic (USA)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PDM US\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: gbw.un383412050b\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PDM US","offers":[{"title":"Default Title","offer_id":51268944953650,"sku":"GBW.UN383412050B","price":372.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308912149.jpg?v=1780710583","url":"https:\/\/voomisupply.com\/products\/pdm-us-gbw-un383412050b-3-8x3-4-40ft-black-line-set","provider":"Voomi Supply","version":"1.0","type":"link"}
