It consists of two refrigerant lines -- a 1\/4-inch liquid line and a 3\/8-inch suction line -- both wrapped in a 1\/2-inch black EZ rubber insulation jacket. The 50-foot length provides enough run for most residential and light commercial wall-mounted or ceiling cassette installations. HVAC technicians use this lineset to connect the indoor air handler to the outdoor condensing unit without field-fabricating separate insulated lines.\u003c\/p\u003e\u003cp\u003eThis lineset is suited for ductless mini-split installations where a single pre-insulated assembly simplifies the refrigerant line run between indoor and outdoor units. The black rubber insulation jacket resists UV exposure and moisture, making it appropriate for exposed or semi-exposed routing on exterior walls or rooftops. The 50-foot length accommodates typical single-zone residential installations and many light commercial applications where the line run from outdoor unit to indoor head does not exceed that distance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-inch liquid line and 3\/8-inch suction line pre-assembled in a single flexible assembly\u003c\/li\u003e\n\u003cli\u003e1\/2-inch black EZ rubber insulation jacket for thermal and UV protection\u003c\/li\u003e\n\u003cli\u003e50-foot length supports standard single-zone mini-split line runs\u003c\/li\u003e\n\u003cli\u003eFlexible construction simplifies routing through walls, conduit, or line hide\u003c\/li\u003e\n\u003cli\u003eBlack finish is suitable for exterior and semi-exposed installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation lineset for residential and light commercial ductless mini-split systems requiring a 1\/4-inch by 3\/8-inch refrigerant line pair.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician with EPA Section 608 certification, as refrigerant line work involves sealed systems. Power down the indoor and outdoor units completely before connecting or disconnecting any refrigerant lines. Avoid sharp bends that could kink the copper tubing; use a tubing bender or gentle radius curves when routing around corners. Pressure-test and evacuate the system to the required vacuum level before releasing refrigerant into the lines.\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: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation 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\u003eInsulation Material\u003c\/strong\u003e: EZ Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJacket Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 223507\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CAMBRIDGE","offers":[{"title":"Default Title","offer_id":51468213223730,"sku":"223507","price":386.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313947889.webp?v=1783914657","url":"https:\/\/voomisupply.com\/products\/cambridge-223507-flex-lineset-1-4x3-8x1-2-in-50-ft-black","provider":"Voomi Supply","version":"1.0","type":"link"}
