The back ferrule is the rear sealing component in a two-ferrule compression fitting assembly, working in conjunction with the front ferrule to grip and seal tubing when the fitting nut is tightened. It is used in instrumentation, fluid handling, and process piping applications where leak-tight, repeatable tube connections are required. Licensed plumbers, pipefitters, and instrumentation technicians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis back ferrule is suited for small-bore tubing applications in both residential and commercial settings, including instrumentation lines, pneumatic controls, hydraulic panels, and analytical equipment. Its 3mm tube OD sizing makes it appropriate for precision tubing runs where compact fittings are required. It is sold individually and must be ordered in a minimum quantity of 5 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance and reliable sealing performance in moderate-pressure service\u003c\/li\u003e\n  \u003cli\u003eDesigned for 3mm outside diameter tubing in two-ferrule compression fitting assemblies\u003c\/li\u003e\n  \u003cli\u003eFunctions as the rear ferrule, providing tube grip and axial support during make-up\u003c\/li\u003e\n  \u003cli\u003eCross-references to Swagelok part number B-3M4-1 for replacement sourcing\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suited for instrumentation and process control tubing installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard two-ferrule compression fitting assemblies with 3mm tube outside diameter tubing.

Shut off system pressure and depressurize all lines before disassembling or replacing ferrule components. Ferrules should not be reused once a fitting has been fully made up, as the ferrule deforms permanently to the tubing during initial assembly. Use appropriate tube preparation tools to ensure a square, clean tube end before insertion into the fitting body.\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: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Tube OD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwagelok Cross-Reference\u003c\/strong\u003e: B-3M4-1\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: HAM-LET\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3600002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HAM-LET","offers":[{"title":"Default Title","offer_id":67912272740658,"sku":"3600002","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94650dfc949ca0a04fc0a035d73ba578_36874d41-12fc-46cd-8b5d-d1476d085248.jpg?v=1791231732","url":"https:\/\/voomisupply.com\/products\/ham-let-3600002-compression-back-ferrule-brass-3mm","provider":"Voomi Supply","version":"1.0","type":"link"}
