The 3BF3-316 designation identifies the ferrule variant used with A-LOK fittings, providing the seating surface behind the nut to secure the tube and contribute to a leak-tight connection in hydraulic and industrial fluid systems. This back ferrule is intended for inch-diameter tube applications within A-LOK assemblies, and it is used together with compatible A-LOK nuts and other ferrules to form a complete, robust junction. The part is specified for inch tubes and is compatible with Parker A-LOK fittings of the corresponding series, supporting reliable performance in applications requiring secure tube termination. When choosing parts for an A-LOK installation, confirm tube size matches the ferrule designation (inch tubes) and that the 3BF3-316 variant aligns with your A-LOK fitting series.\u003c\/p\u003e\u003c\/div\u003e","brand":"Parker","offers":[{"title":"New","offer_id":46286205092074,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-027.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/parker-hannifin-corporation-3bf3-316-a-lok-tube-back-ferrule","provider":"GTG Hardware","version":"1.0","type":"link"}
