It connects tube to tube without soldering, flaring, or threading, making it a reliable choice for instrumentation, HVAC, plumbing, and industrial fluid systems. Constructed from stainless steel, it delivers corrosion resistance and durability in demanding service environments. With a maximum working pressure rating of 10300 psi, this union is suited for high-pressure applications where fitting integrity is critical. Installation requires only basic hand tools and correct tube preparation.\u003c\/p\u003e\n\u003cp\u003eThis compression tube union is used in residential and commercial applications where leak-tight tube connections are required. Typical installations include instrument tubing runs, refrigeration sensing lines, hydraulic control lines, and general fluid distribution systems. The compression x compression end configuration allows the fitting to join two tube ends inline without the need for additional adapters. It is well suited for tight-space routing where a straight union connection simplifies assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel construction provides corrosion resistance for demanding service environments\u003c\/li\u003e\n  \u003cli\u003eCompression x compression end connections eliminate the need for soldering, flaring, or threading\u003c\/li\u003e\n  \u003cli\u003eMaximum working pressure of 10300 psi supports high-pressure fluid and instrumentation systems\u003c\/li\u003e\n  \u003cli\u003eInline union configuration for straight tube-to-tube connections\u003c\/li\u003e\n  \u003cli\u003eCompact design suitable for installations with limited clearance\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 standard compression tube fitting systems where a stainless steel union connection is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified plumber, pipefitter, or instrumentation technician familiar with compression fitting assembly procedures. Shut off and depressurize the system completely before removing any existing fittings or tubes. Ensure tube ends are cut cleanly and squarely, and that ferrules are seated correctly before tightening the compression nut. Do not overtighten compression fittings, as this can deform ferrules and compromise the seal.\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\u003eMaximum Working Pressure\u003c\/strong\u003e: 10300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0516 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: 4-1 HBZ-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541435089202,"sku":"4-1 HBZ-SS","price":69.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/212089a6a0e0b8d2b42e3726e5509ea0_8cb39a6a-0a62-4d9f-992c-da151ef8d62e.jpg?v=1785876057","url":"https:\/\/voomisupply.com\/products\/parker-4-1-hbz-ss-compression-tube-union-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
