Built from steel, this union accepts 8 mm outside diameter tubing and is rated for a maximum working pressure of 500 bar. The bite-type design eliminates the need for flared tube ends, using a ferrule that bites into the tube wall to create a reliable, leak-resistant seal. It is sized with a 14 mm hex for standard wrench engagement. Hydraulic technicians, industrial maintenance pipefitters, and fluid power specialists install this fitting in demanding high-pressure fluid or pneumatic circuit applications.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for use in industrial, mobile hydraulic, and fluid power systems where flareless tube connections are required. The straight union configuration joins two runs of 8 mm OD tubing in a single inline path. It is appropriate for both new installation and replacement service on hydraulic power units, machine tool circuits, and process instrumentation lines. The steel construction supports use in environments where high working pressures and mechanical durability are primary concerns.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlareless bite-type design eliminates tube flaring during assembly\u003c\/li\u003e\n  \u003cli\u003eRated to 500 bar maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eAccepts 8 mm outside diameter tubing\u003c\/li\u003e\n  \u003cli\u003eStraight union configuration for inline tube-to-tube connection\u003c\/li\u003e\n  \u003cli\u003e14 mm hex size for standard wrench engagement\u003c\/li\u003e\n  \u003cli\u003eSteel construction for high-pressure mechanical durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flareless bite-type union for use with 8 mm OD steel tubing in high-pressure hydraulic and instrumentation plumbing systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or industrial pipefitter. Depressurize and isolate the hydraulic or fluid circuit completely before disconnecting any existing fittings or tubing. Ensure tube ends are cut cleanly and squarely, and that tubing is properly inserted to the tube stop before tightening the nut to allow the ferrule to bite correctly. Follow the fitting manufacturer's prescribed assembly procedure for bite-type fittings, as over-tightening can damage the ferrule or tube wall.\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\u003eFitting Shape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 500 bar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 14 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 25 mm\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-00557\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542067511602,"sku":"PT-00557","price":50.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c5699075f67d2b6b8559e1f7d47143f_57375c44-bc5f-4b17-816e-028a0815ea68.jpg?v=1785891095","url":"https:\/\/voomisupply.com\/products\/parker-pt-00557-flareless-bite-type-tube-union-8mm-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
