This fitting accepts a 3\/4-inch outside diameter tube on one end and a 1\/2-inch outside diameter tube on the other, making it a reducing union suited for systems that require a step-down in tubing size without threaded connections. It carries a maximum working pressure of 5800 psi, making it appropriate for high-pressure fluid and gas lines. Plumbers, pipefitters, and mechanical contractors install this type of fitting in instrumentation, hydraulic, and process piping systems where leak-free, reusable connections are required.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and commercial applications where stainless steel construction is specified for corrosion resistance or compatibility with aggressive media. Common install scenarios include instrument tubing runs, compressed air lines, chemical distribution systems, and OEM equipment assemblies. The compression-by-compression configuration allows field installation without soldering, brazing, or special tooling, which makes it practical for service and maintenance work as well as new construction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel construction provides corrosion resistance for demanding fluid and gas service\u003c\/li\u003e\n  \u003cli\u003eCompression x compression end connections on both sides — no soldering or brazing required\u003c\/li\u003e\n  \u003cli\u003eReducing union joins 3\/4-inch OD tube to 1\/2-inch OD tube in a single fitting\u003c\/li\u003e\n  \u003cli\u003eRated to 5800 psi maximum working pressure for high-pressure system applications\u003c\/li\u003e\n  \u003cli\u003eReusable fitting design supports service and maintenance disconnects\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression tube union for instrumentation, hydraulic, and process piping applications using 3\/4-inch and 1\/2-inch outside diameter tubing with compression-style connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified plumbers, pipefitters, or instrumentation technicians. Depressurize and isolate the line completely before disassembling any existing fitting or installing this union. Ensure tubing ends are cut square, deburred, and free of contaminants before seating into the compression fitting. Follow applicable IPC and ASME B31.3 guidelines for the service pressure and media involved.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\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 x 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 5800 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2775 pounds\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12-8 HBZ-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544460230962,"sku":"12-8 HBZ-SS","price":142.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f9aa17ea8c56139b6854e29e78239c0_2a76d6b1-32ce-4fef-8833-057b40554fce.jpg?v=1785927096","url":"https:\/\/voomisupply.com\/products\/parker-12-8-hbz-ss-compression-tube-union-3-4x1-2-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
