This adapter is rated for use with A2L low-GWP refrigerants, making it suitable for modern systems that use mildly flammable next-generation refrigerants such as R-32 or R-454B. HVAC technicians use this fitting when connecting indoor unit refrigerant lines to field piping of a larger diameter. It is sold individually and is an OEM-specified component for proper system assembly.\u003c\/p\u003e\u003cp\u003eThis joint pipe is intended for use in residential and light commercial ductless or multi-split refrigerant systems where the indoor unit connection port is 1\/4 inch and the field refrigerant line is 3\/8 inch. It is particularly relevant in installations involving newer A2L-rated equipment where OEM-specified fittings are required to maintain refrigerant system integrity and comply with equipment warranty and listing requirements. HVAC technicians performing new installations or refrigerant circuit work on compatible Mitsubishi Electric systems would source this fitting as part of the line set connection assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTransitions refrigerant line from 1\/4-inch unit port to 3\/8-inch field pipe\u003c\/li\u003e\n\u003cli\u003eRated for A2L mildly flammable refrigerant service\u003c\/li\u003e\n\u003cli\u003eOEM component for proper system fit and refrigerant compatibility\u003c\/li\u003e\n\u003cli\u003eSold individually for precise quantity ordering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Mitsubishi Electric split and multi-split HVAC systems utilizing A2L refrigerants where a 1\/4-inch to 3\/8-inch refrigerant line transition is required.

Recover all refrigerant and isolate the system before disconnecting or modifying any refrigerant circuit components. Follow the equipment manufacturer installation manual for torque and connection procedures specific to the system. Verify that all fittings and line set components are rated for the refrigerant type in use before completing the circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit-Side Connection Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe-Side Connection Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefrigerant Compatibility\u003c\/strong\u003e: A2L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITSUBISHI ELECTRIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: pac-sj87rj-e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51383348232498,"sku":"PAC-SJ87RJ-E","price":32.97,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/mitsubishi-electric-pac-sj87rj-e-joint-pipe-1-4-to-3-8-inch-a2l","provider":"Voomi Supply","version":"1.0","type":"link"}
