This steel ring seats and bites into the outer wall of an 8 mm OD tube during assembly, creating a leak-resistant, vibration-tolerant connection without the need to flare the tubing. It is rated for a maximum working pressure of 500 bar and measures 9 mm in overall length. Installation is performed by licensed plumbers, hydraulic technicians, and instrumentation mechanics working on steel tube assemblies in industrial, mobile, or process-control systems.\u003c\/p\u003e\u003cp\u003eThis progressive ring is suited for high-pressure tube connections in industrial and commercial applications. The flareless bite-type design eliminates the need for tube flaring operations on-site, making it a practical choice for field assembly and maintenance work on hydraulic circuits, fluid power systems, and instrumentation lines that require reliable, high-pressure tube terminations. The ring is compatible with 8 mm OD tube in flareless fitting systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFlareless bite-type design eliminates on-site tube flaring\u003c\/li\u003e\n\u003cli\u003eRated for maximum working pressure of 500 bar\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in high-pressure environments\u003c\/li\u003e\n\u003cli\u003e8 mm tube OD sizing for precise fitment in metric tube systems\u003c\/li\u003e\n\u003cli\u003eCompact 9 mm overall length for tight installation spaces\u003c\/li\u003e\n\u003cli\u003eSold in packages of 10 rings per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service component for flareless bite-type tube fitting assemblies using 8 mm OD steel tubing in high-pressure hydraulic and instrumentation systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or licensed plumber familiar with flareless tube fitting assembly procedures. Depressurize and isolate the hydraulic or fluid system completely before disassembly or fitting replacement. Follow the fitting manufacturer's assembly torque and presetting procedure for bite-type rings to ensure proper bite engagement without over-tightening. Applicable work should conform to relevant fluid power and plumbing codes for the jurisdiction and system pressure class.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Progressive Ring, Flareless Bite-Type\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 500 bar\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: 10 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-00451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540277887282,"sku":"PT-00451","price":25.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/980e1a2db7e58fcb07e0108964730d9d.jpg?v=1785851037","url":"https:\/\/voomisupply.com\/products\/parker-pt-00451-bite-type-progressive-ring-8mm-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
