It accepts a 5\/16-inch outside diameter tube on one end and a 1\/4-inch outside diameter tube on the other, making it a reducing union suitable for applications where tubing sizes transition. Rated to 8100 psi maximum working pressure, this fitting is built for demanding service in hydraulic, instrumentation, or high-pressure fluid systems. Stainless steel construction provides corrosion resistance in wet, chemical, or outdoor environments. Installation requires no welding or brazing — hand tools are sufficient for assembly. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for use in instrumentation tubing systems, high-pressure hydraulic lines, process fluid circuits, and pneumatic control lines where a leak-free compression connection is required. The compression-by-compression end configuration makes it appropriate for joining two tube runs without special adapters. Its stainless steel body makes it a good choice for corrosive media or sanitary applications where carbon steel fittings are not acceptable. It is packaged as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing union joins 5\/16-inch OD tube to 1\/4-inch OD tube in a single fitting\u003c\/li\u003e\n  \u003cli\u003e8100 psi maximum working pressure rating for high-pressure service\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction resists corrosion in chemical, wet, and outdoor environments\u003c\/li\u003e\n  \u003cli\u003eCompression x compression end connections allow tool-assisted assembly without welding or brazing\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.087 pounds — minimal load on tubing runs\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 fluid tubing systems using 5\/16-inch and 1\/4-inch outside diameter tubing with compression-style end connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed pipefitter, plumber, or instrumentation technician familiar with compression fitting assembly practices. Depressurize and isolate the tubing circuit completely before disassembling any existing fittings. Use two wrenches when tightening compression fittings to prevent tube rotation and avoid over-tightening, which can deform the ferrule and cause leaks. Follow applicable codes such as ASME B31.1 or B31.3 for pressure piping systems as required by the installation environment.\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: 5\/16 x 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 8100 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.087 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\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: 5-4 HBZ-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540198654258,"sku":"5-4 HBZ-SS","price":70.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/128ebe6abb0177085095072fc8532436.jpg?v=1785848666","url":"https:\/\/voomisupply.com\/products\/parker-5-4-hbz-ss-compression-tube-union-ss-5-16x1-4-8100psi","provider":"Voomi Supply","version":"1.0","type":"link"}
