This ring serves as the compression element in a flareless fitting system, biting into the tube wall as the fitting nut is torqued down to create a leak-resistant mechanical connection without requiring a flared tube end. It is a precision-machined component used by hydraulic system technicians, industrial maintenance professionals, and fluid system installers working with metric tube lines.\u003c\/p\u003e\n\u003cp\u003eThis progressive ring is suited for metric tube fitting assemblies in hydraulic power units, industrial machinery, and fluid transfer systems where flareless connections are specified. It is compatible with 18 mm OD tubing in applications governed by DIN or equivalent flareless fitting standards. Sold in packages of five, this ring is a practical quantity for service shops and system builders managing multiple connections or performing multiple repairs on the same line size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBite-type progressive design creates a secure, leak-resistant grip on 18 mm OD tubing without flaring\u003c\/li\u003e\n  \u003cli\u003eFlareless construction eliminates the need for tube flaring equipment during assembly\u003c\/li\u003e\n  \u003cli\u003eDesigned for metric tube fitting systems consistent with flareless DIN-style fitting standards\u003c\/li\u003e\n  \u003cli\u003ePackaged in a quantity of five to support multi-connection service jobs\u003c\/li\u003e\n  \u003cli\u003eLightweight component at 0.01 pounds per unit for ease of handling and inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and service component for flareless bite-type tube fitting assemblies using 18 mm outside diameter metric tubing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hydraulic system technicians or fluid system mechanics familiar with flareless fitting assembly procedures. Before servicing any hydraulic line, depressurize the system completely and follow applicable lockout\/tagout procedures. The progressive ring must be properly seated on the tube before engaging the fitting body and nut. Do not reuse a ring that has already been fully swaged onto a tube, as the bite geometry will not seat correctly on a new tube surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Progressive Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 18 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Style\u003c\/strong\u003e: Flareless Bite-Type\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  \u003cli\u003e\n\u003cstrong\u003eProduct Service Code\u003c\/strong\u003e: 4720\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-00477\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544057938226,"sku":"PT-00477","price":60.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_ad2b790e-94fb-492e-84d1-2cc6dfa73ad3.jpg?v=1785923386","url":"https:\/\/voomisupply.com\/products\/parker-pt-00477-flareless-bite-type-progressive-ring-18mm","provider":"Voomi Supply","version":"1.0","type":"link"}
