Constructed from brass, this union provides a leak-resistant mechanical seal without soldering or welding. It is rated for a maximum working pressure of 1900 psi, making it suitable for demanding fluid and gas distribution lines in HVAC, plumbing, and related mechanical systems. Licensed plumbers, pipefitters, and HVAC technicians install this fitting when a reliable, field-serviceable tube connection is required in a pressurized system.\u003c\/p\u003e\u003cp\u003eThis fitting is used in residential and commercial applications where copper or compatible tubing with a 3\/4 inch outside diameter must be connected inline. Common install scenarios include refrigeration line connections, instrumentation tubing runs, and hydraulic or pneumatic distribution circuits that require a removable union joint. The compression design allows the fitting to be assembled and disassembled with standard hand tools without damaging the tubing ends.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCompression x compression end connections on both sides for tool-accessible assembly\u003c\/li\u003e\n\u003cli\u003eBrass construction offers corrosion resistance in wet and fluid-handling environments\u003c\/li\u003e\n\u003cli\u003e1900 psi maximum working pressure rating for high-pressure line applications\u003c\/li\u003e\n\u003cli\u003eAccepts tubing with a 3\/4 inch outside diameter\u003c\/li\u003e\n\u003cli\u003eNo soldering or brazing required during installation\u003c\/li\u003e\n\u003cli\u003eField-serviceable union design allows disassembly and reassembly without cutting tubing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation compression union for systems using 3\/4 inch outside diameter tubing with compression-style fittings.

Shut off and depressurize the system completely before disassembling or installing any compression fitting. Use two wrenches when tightening to prevent tubing rotation and avoid over-tightening, which can deform the ferrule and cause leaks. Verify that tubing ends are cut square, deburred, and fully seated before applying torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Compression x Compression\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1900 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Reference Part Number\u003c\/strong\u003e: B-1210-6 (Swagelok)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12SC12-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542942449970,"sku":"12SC12-B","price":60.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c8825a03afdecbf71330fd6010e2949.jpg?v=1785911785","url":"https:\/\/voomisupply.com\/products\/parker-12sc12-b-compression-tube-union-3-4-inch-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
