Back ferrules are the rear sealing component in two-ferrule compression fittings, working in tandem with a front ferrule to create a leak-tight mechanical connection when the fitting nut is tightened. This ferrule is machined from 316 stainless steel and meets multiple ASTM and DIN material standards, making it suitable for demanding fluid and gas instrumentation systems. It is typically installed by licensed plumbers, pipefitters, or instrumentation technicians working on process, pneumatic, or high-purity tubing runs.\u003c\/p\u003e\n\u003cp\u003eThis back ferrule is sized for 3\/4 inch tube OD and is compatible with standard two-ferrule compression fitting assemblies used in industrial, commercial, and process instrumentation applications. The 1-20 UNF thread standard and overall length of 0.2902 inches conform to widely used compression fitting geometry. Applications include process piping, pneumatic control lines, hydraulic instrumentation, and chemical distribution systems where a reliable tube seal is required. The Swagelok equivalent part number is SS-1214-1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316 stainless steel construction meets ASTM A182, A213, A269, A276, A479 and DIN EN10122-5, DIN EN10272 standards\u003c\/li\u003e\n  \u003cli\u003eSized for 3\/4 inch tube outside diameter compression fittings\u003c\/li\u003e\n  \u003cli\u003eOverall length of 0.2902 inches (7.37 mm) for precise ferrule seat engagement\u003c\/li\u003e\n  \u003cli\u003e1-20 UNF thread standard for compatibility with standard compression fitting bodies and nuts\u003c\/li\u003e\n  \u003cli\u003eSingle-piece back ferrule design provides reliable rear tube grip in two-ferrule assemblies\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 27121700 and Product Service Code 4720 for procurement and cataloging\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement back ferrule for standard two-ferrule compression tube fittings using 3\/4 inch tube OD.

Before servicing any compression fitting, depressurize and isolate the line completely. Back ferrules must be installed in the correct orientation within the fitting body — reversing front and back ferrules will result in a failed seal. Follow the fitting manufacturer's assembly instructions for proper nut turn from finger-tight to avoid over-swaging the ferrule.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Back Ferrule\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Tube OD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.2902 inches (7.37 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-20 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM A182, ASTM A213, ASTM A269, ASTM A276, ASTM A479, DIN EN10122-5, DIN EN10272\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SS-RF-FT12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714316894514,"sku":"SS-RF-FT12","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e4a8f589f8e90d613d6666307ff8050.jpg?v=1788499377","url":"https:\/\/voomisupply.com\/products\/value-collection-ss-rf-ft12-compression-back-ferrule-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
