It features a 3\/8-inch liquid line and a 3\/4-inch suction line, both insulated with 3\/4-inch black polyethylene hard-shell insulation rated for R-410A refrigerant systems. The line set runs 40 feet in length and ships ready to install with plain end connections on both sides. The rugged, anti-tear exterior simplifies pulling through walls and chases, and the UV-resistant jacket is suitable for exposed outdoor runs. Insulation is marked at every foot for quick measurement on the job.\u003c\/p\u003e\n\u003cp\u003eThis line set is suited for ductless mini-split systems, VRF commercial systems, and split-system air conditioners and heat pumps. The 40-foot length accommodates typical residential side-of-structure and rooftop condenser placements where the air handler and outdoor unit are separated by moderate distances. Both copper lines conform to ASTM B743\/B88 material specifications, and the assembly meets ASTM E84\/C1427 and UL standards for fire and insulation performance. It is appropriate for licensed HVAC technicians installing new systems or replacing deteriorated line sets on existing equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-inch liquid line and 3\/4-inch suction line in a single pre-insulated assembly\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch black polyethylene hard-shell insulation rated for R-410A systems\u003c\/li\u003e\n  \u003cli\u003eUV-resistant jacket suitable for outdoor and exposed-run applications\u003c\/li\u003e\n  \u003cli\u003eRugged anti-tear exterior designed to reduce damage during installation pulls\u003c\/li\u003e\n  \u003cli\u003eInsulation marked every foot for accurate field measurement\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM E84\/C1427 and UL standards; copper conforms to ASTM B743\/B88\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with ductless mini-split systems, VRF commercial systems, and split-system air conditioners and heat pumps using R-410A refrigerant.

Recover any existing refrigerant charge before disconnecting an existing line set. Plain ends require field brazing or flaring to connect to system components — verify that fitting sizes match the equipment manufacturer specifications before cutting. Support the line set at regular intervals per local code to prevent sagging and vibration wear over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Line Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuction Line Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Thickness\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\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Material\u003c\/strong\u003e: Black Polyethylene Hard Shell\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Plain End x Plain End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant Compatibility\u003c\/strong\u003e: R-410A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: ASTM B743\/B88\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ASTM E84\/C1427, UL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Ductless Mini-Split System, VRF Commercial System, Split System Air Conditioner and Heat Pump\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-LEE INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 061212400B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CAMBRIDGE-LEE INDUSTRIES","offers":[{"title":"Default Title","offer_id":51283922518322,"sku":"061212400B","price":343.86,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278361.jpg?v=1781063307","url":"https:\/\/voomisupply.com\/products\/cambridge-lee-industries-061212400b-line-set-40-feet","provider":"Voomi Supply","version":"1.0","type":"link"}
