It accepts a 3\/8-inch outside diameter tube on one end and a 5\/16-inch outside diameter tube on the other, making it suitable for reducing union applications in instrumentation, hydraulic, and pneumatic tubing systems. Rated to a maximum working pressure of 6600 psi, this fitting is built for high-pressure service. It is typically installed by plumbers, pipefitters, or instrumentation technicians working with stainless steel tubing in industrial or process environments.\u003c\/p\u003e\n\u003cp\u003eThis union fitting is used in applications requiring a leak-tight, tool-assisted connection between two compression tubes of differing outside diameters. Common installation scenarios include instrument tubing runs, fluid power circuits, and process control lines where stainless steel is specified for corrosion resistance or cleanliness requirements. The compression-by-compression end configuration allows field assembly without welding or brazing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel construction for corrosion resistance in demanding service environments\u003c\/li\u003e\n  \u003cli\u003eCompression x compression end connections for tool-assisted, no-braze field assembly\u003c\/li\u003e\n  \u003cli\u003eReducing union design accepts 3\/8-inch OD tube on one end and 5\/16-inch OD tube on the other\u003c\/li\u003e\n  \u003cli\u003eRated to 6600 psi maximum working pressure for high-pressure instrumentation and fluid systems\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.11 pounds for easy handling in tight tubing runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for stainless steel compression tubing systems using 3\/8-inch and 5\/16-inch outside diameter tube.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber, pipefitter, or instrumentation technician. Depressurize and isolate the tubing circuit completely before disassembling any compression fittings. Ensure tube ends are cut square and deburred before seating into the compression ferrule to achieve a proper seal. Follow applicable plumbing and instrumentation codes for high-pressure tubing assembly and inspection.\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\/8 x 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 6600 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: 6-5 HBZ-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542712025394,"sku":"6-5 HBZ-SS","price":47.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39768b4607b4a8495f34d51ac90f4b44.jpg?v=1785905116","url":"https:\/\/voomisupply.com\/products\/parker-6-5-hbz-ss-compression-tube-union-ss-3-8x5-16-6600psi","provider":"Voomi Supply","version":"1.0","type":"link"}
