Built from steel, this union accepts 12 mm outside diameter tubing and holds a maximum working pressure of 400 bar. The bite-type design uses a ferrule that bites into the tube wall during assembly, eliminating the need for pre-flaring. Installation is straightforward and repeatable, making it a reliable choice for field and shop assembly on industrial fluid lines. Licensed plumbers, pipefitters, and hydraulic system technicians are the primary installers for this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for use in hydraulic circuits, instrumentation tubing runs, and fluid power systems where a secure, leak-resistant union is required without a flared tube end. The straight configuration keeps the flow path direct, making it appropriate for panel-mounted assemblies, machine tool plumbing, and process control lines operating at elevated pressures. Its compact overall length of 28 mm keeps installation envelopes tight in confined spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlareless bite-type design eliminates pre-flaring of tube ends\u003c\/li\u003e\n  \u003cli\u003eRated to 400 bar maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eAccepts 12 mm outside diameter tubing\u003c\/li\u003e\n  \u003cli\u003eStraight union configuration for inline tube-to-tube connections\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in high-pressure hydraulic environments\u003c\/li\u003e\n  \u003cli\u003e19 mm hex size for standard wrench engagement during assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for industrial hydraulic and instrumentation tube assemblies using 12 mm OD tubing with flareless bite-type connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed pipefitters or hydraulic system technicians familiar with flareless compression fitting assembly procedures. Depressurize and isolate the hydraulic or fluid circuit completely before disassembling any existing tube connections. Follow the fitting manufacturer assembly procedure for ferrule pre-setting to ensure proper bite and seal. Applicable installations should conform to relevant fluid power and piping codes for the system operating pressure.\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\u003eConnection Style\u003c\/strong\u003e: Flareless Bite-Type\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Shape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 400 bar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 19 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 28 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: PT-00559\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538920145202,"sku":"PT-00559","price":76.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c5699075f67d2b6b8559e1f7d47143f_da6dc945-d54f-4699-92b9-752ea08c8736.jpg?v=1785829665","url":"https:\/\/voomisupply.com\/products\/parker-pt-00559-flareless-bite-type-tube-union-12mm-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
