The front ferrule seats between the compression nut and the tube, creating a leak-tight mechanical seal when the fitting is tightened. Manufactured from stainless steel, this ferrule provides corrosion resistance suitable for demanding fluid and gas handling applications. It is compatible with 3\/8-inch outside diameter tubing and is sold in a package of 5 pieces, making it practical for service technicians and installers who routinely stock compression fitting components.\u003c\/p\u003e\n\u003cp\u003eThis front ferrule is used in compression-style tube connections found in HVAC, plumbing, instrumentation, and industrial process piping systems. It is suited for both residential and light commercial applications where a reliable, reusable tube fitting is required. The ferrule cross-references to Swagelok part number SS-603-1, making it a recognized replacement option in instrumentation and fluid system work where Swagelok-style compression hardware is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel construction for corrosion resistance in wet, chemical, and outdoor environments\u003c\/li\u003e\n  \u003cli\u003eFits 3\/8-inch outside diameter tubing for precise compression sealing\u003c\/li\u003e\n  \u003cli\u003eFront ferrule design creates a positive, leak-tight seat when compressed against the fitting body\u003c\/li\u003e\n  \u003cli\u003eCross-references to Swagelok part number SS-603-1\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 5 pieces to support service kit stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with compression fitting assemblies accepting a 3\/8-inch outside diameter tube front ferrule.

Shut off all pressure to the line and depressurize the system before disassembling any compression fitting. Seat the front ferrule squarely on the tube before threading the compression nut to avoid cocking or improper sealing. Do not reuse a ferrule that has been fully swaged onto tubing, as reshaping a compressed ferrule will compromise the seal integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Front Ferrule\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Compression Cap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\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: BRENNAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KP4311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BRENNAN INDUSTRIES","offers":[{"title":"Default Title","offer_id":67913060876594,"sku":"KP4311","price":25.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25f317b7210392edf9fc27da3e7d8aef.jpg?v=1791242135","url":"https:\/\/voomisupply.com\/products\/brennan-kp4311-compression-front-ferrule-3-8-in-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
