The lineset includes a 0.25-inch liquid line and a 0.5-inch suction line, both protected by Armashield insulation for thermal efficiency and moisture resistance. Double flare nuts are pre-installed on both lines for a secure, leak-resistant connection at the service valves. This lineset ships without communication or power wire, making it appropriate for systems that route wiring separately. HVAC technicians install this lineset during new mini split installations or refrigerant line replacements.\u003c\/p\u003e\n\u003cp\u003eThe 221982 lineset is suited for residential and light-commercial ductless mini split installations where a 25-foot line run is required. The 0.25-inch by 0.5-inch line diameter pairing is a common configuration for single-zone mini split systems in the 9,000 to 18,000 BTU\/h range. The Armashield insulation jacket helps maintain system efficiency by minimizing heat gain on the suction line and heat loss on the liquid line across the full 25-foot run.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e25-foot pre-cut lineset length for standard single-zone mini split runs\u003c\/li\u003e\n  \u003cli\u003e0.25-inch liquid line and 0.5-inch suction line diameter pairing\u003c\/li\u003e\n  \u003cli\u003ePre-installed double flare nuts on both lines for secure valve connections\u003c\/li\u003e\n  \u003cli\u003eArmashield insulation jacket on both lines for thermal protection\u003c\/li\u003e\n  \u003cli\u003eNo wire included — supports separate wiring routing configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation lineset for residential and light-commercial ductless mini split systems requiring a 0.25-inch by 0.5-inch line pair at a 25-foot run length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician certified to handle refrigerant per EPA Section 608 requirements. Shut off and lock out power to both the indoor and outdoor units before making any line connections. Inspect flare seats and double flare nuts before torquing connections to service valve specifications provided by the equipment manufacturer. Avoid sharp bends in the copper lines during routing to prevent restriction or kinking.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Line Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuction Line Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLineset Length\u003c\/strong\u003e: 25 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Type\u003c\/strong\u003e: Armashield\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlare Nut Type\u003c\/strong\u003e: Double Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 12.5 inches\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: CAMBRIDGE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 221982\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CAMBRIDGE","offers":[{"title":"Default Title","offer_id":51506755436850,"sku":"221982","price":240.84,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/cambridge-221982-mini-split-lineset-0-25x0-5-in-25-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
