It connects 3\/8-inch OD tubing on one end to 1\/4-inch OD tubing on the other using compression-style end connections, eliminating the need for solder, flare tools, or welding. Rated to 6600 psi maximum working pressure, this union is built for demanding fluid and gas system applications where leak-free performance and corrosion resistance are critical. Plumbers, HVAC technicians, and instrumentation specialists routinely install this type of fitting in high-pressure line assemblies.\u003c\/p\u003e\n\u003cp\u003eThis fitting suits residential and commercial installations where stainless steel is specified for corrosion resistance or system cleanliness requirements. Typical applications include instrument tubing runs, refrigeration and pneumatic lines, chemical feed systems, and hydraulic circuits where a reducing union is needed to transition between two tube sizes. The compression design allows installation and future disassembly without specialized tooling beyond a wrench.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel construction for corrosion resistance in harsh or chemically aggressive environments\u003c\/li\u003e\n  \u003cli\u003eCompression x compression end connections on both sides for tool-free tube joining\u003c\/li\u003e\n  \u003cli\u003eReducing union transitions 3\/8-inch OD tubing to 1\/4-inch OD tubing in a single fitting\u003c\/li\u003e\n  \u003cli\u003e6600 psi maximum working pressure rating supports high-pressure system applications\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.71 inches allows installation in compact spaces\u003c\/li\u003e\n  \u003cli\u003eReusable and field-serviceable without cutting or reflaring tubing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression tube union compatible with 3\/8-inch OD and 1\/4-inch OD tubing in compression fitting systems requiring a stainless steel reducing union.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers, HVAC technicians, or instrumentation technicians depending on the system. Depressurize and isolate the tubing circuit fully before disconnecting or installing any compression fitting. Ensure tube ends are cut square and deburred before seating into the compression ferrule to achieve a proper seal. Follow applicable codes including ASME B31 piping standards or local jurisdiction requirements for high-pressure tubing systems.\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 1\/4 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\u003eOverall Length\u003c\/strong\u003e: 1.71 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: 6-4 HBZ-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543016669490,"sku":"6-4 HBZ-SS","price":64.26,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc082243521397efb2b68216ed50891d.jpg?v=1785913738","url":"https:\/\/voomisupply.com\/products\/parker-6-4-hbz-ss-compression-tube-union-3-8x1-4-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
