This lineset features a 1\/4-inch liquid line and a 1\/2-inch suction line, with a total run length of 15 feet. It is supplied without communication wire and includes double flare nuts on both lines for a secure, leak-resistant connection. HVAC technicians working on residential and light-commercial ductless installations will find this lineset ready for field use straight out of the box.\u003c\/p\u003e\n\u003cp\u003eThis lineset is suited for residential ductless mini split installations where a 15-foot run from the indoor air handler to the outdoor unit is appropriate. The 1\/4-inch by 1\/2-inch line diameter combination covers a common range of single-zone mini split system capacities. This part supersedes the older part number 222818 and also cross-references as 408K0150B3B6L and B141212015, making it a direct drop-in for installations that previously used those identifiers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-inch liquid line and 1\/2-inch suction line for standard mini split applications\u003c\/li\u003e\n  \u003cli\u003e15-foot pre-cut length reduces field measuring and cutting time\u003c\/li\u003e\n  \u003cli\u003eDouble flare nuts included on both lines for a reliable, leak-resistant seal\u003c\/li\u003e\n  \u003cli\u003eSupplied without communication wire — compatible with systems using separate low-voltage wiring\u003c\/li\u003e\n  \u003cli\u003eSupersedes part number 222818 for direct replacement use\u003c\/li\u003e\n  \u003cli\u003eCross-references: 408K0150B3B6L, B141212015\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis lineset replaces CAMBRIDGE part number 222818 and cross-references as 408K0150B3B6L and B141212015.

Power down both the indoor and outdoor units at the disconnect before making any line connections. Ensure all flare connections are seated and torqued using a calibrated torque wrench to the equipment manufacturer specifications — do not overtighten. Leak-test the completed lineset with dry nitrogen before evacuating and charging the system.\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\u003eLineset Length\u003c\/strong\u003e: 15 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Double Flare Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSupersedes Part Number\u003c\/strong\u003e: 222818\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 75865914348\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: 223509\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CAMBRIDGE","offers":[{"title":"Default Title","offer_id":51468625838386,"sku":"223509","price":181.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/minisplit-lineset_a8454b06-0d26-4cec-80ad-f392eefcbf47.jpg?v=1783919270","url":"https:\/\/voomisupply.com\/products\/cambridge-223509-mini-split-lineset-1-4x1-2-in-15-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
