It transitions a 1\/2-inch flare connection to a 1\/4-inch flare connection, allowing technicians to join mismatched line sizes without adapters or field fabrication. Rated to 700 psi maximum working pressure, this fitting is built for demanding service conditions. Manufactured from brass, it resists corrosion and holds up in both high-pressure and moderate-temperature environments. HVAC technicians and plumbers install this fitting when routing refrigerant lines or gas piping that requires a size reduction at a union joint.\u003c\/p\u003e\n\u003cp\u003eThis reducing union is suited for residential and light commercial HVAC systems, refrigeration piping, and gas supply lines where a flare-to-flare connection is required between different tube sizes. The flare joint design eliminates the need for solder or thread sealant at the connection point, making it a practical choice for field service work and system modifications. It is compatible with standard flare fittings on 1\/2-inch and 1\/4-inch copper or compatible tubing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces a 1\/2-inch flare connection to a 1\/4-inch flare connection in a single fitting\u003c\/li\u003e\n  \u003cli\u003e700 psi maximum working pressure for high-pressure service\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eFlare X flare connection type requires no solder or thread compound\u003c\/li\u003e\n  \u003cli\u003eUniversal part number UR2-84 for cross-reference identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for HVAC, refrigeration, and gas piping applications requiring a 1\/2-inch by 1\/4-inch flare-to-flare reducing union connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber in accordance with applicable mechanical codes. Always depressurize and evacuate the system before disconnecting or installing flare fittings. Use a properly sized flaring tool to ensure clean, leak-free flare seats on both tube ends. Inspect flare seats for burrs or damage before assembly and tighten flare nuts to the fitting without over-torquing, which can distort the flare and cause leaks.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 700 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Connection Size\u003c\/strong\u003e: 1\/2 inch X 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Connection Type\u003c\/strong\u003e: Flare X Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBasic Fitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecific Fitting Type\u003c\/strong\u003e: Reducing Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniversal Part Number\u003c\/strong\u003e: UR2-84\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: MUELLER STREAMLINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A 00356\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51524864213298,"sku":"A 00356","price":20.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19dd554b95fa29658a0c2ccb5a1e5684.jpg?v=1785459981","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-a-00356-brass-reducing-union","provider":"Voomi Supply","version":"1.0","type":"link"}
