The ferrule seats against the fitting body as the compression nut is tightened, biting into the outer diameter of the tubing to hold pressure and prevent leakage. Sized for 1\/4-inch outside diameter tubing, this ferrule is constructed from brass, making it suitable for a wide range of fluid and gas line applications. Sold in a pack of 10, it is a standard consumable stocked by plumbers, HVAC technicians, and pipefitters for routine service and new installations.\u003c\/p\u003e\n\u003cp\u003eThis ferrule is used in compression fittings on copper, brass, and compatible soft-metal tubing with a 1\/4-inch outside diameter. Typical applications include refrigerant-side instrumentation lines, pneumatic control tubing, fuel gas pilot lines, water supply connections, and instrumentation tubing runs in both residential and light commercial systems. It is a direct-use component in any compression fitting assembly that calls for a separate ferrule rather than a captured or pre-installed design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance and reliable deformation characteristics for a secure compression seal\u003c\/li\u003e\n  \u003cli\u003eSized for 1\/4-inch outside diameter tubing to match standard compression fitting bodies\u003c\/li\u003e\n  \u003cli\u003eCompatible with common compression nut and fitting body assemblies used in plumbing, HVAC, and instrumentation\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 10 for convenient stocking and repetitive service work\u003c\/li\u003e\n  \u003cli\u003eFitting type classification 4720 per Product Service Code, aligning with hose, pipe, and tube fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement ferrule for standard compression tube fitting assemblies using 1\/4-inch outside diameter tubing.

Before servicing any compression fitting, isolate and depressurize the line and shut off all fluid or gas supply upstream of the connection point. Do not over-tighten the compression nut, as excess torque can deform the ferrule beyond its seating geometry and compromise the seal. Follow applicable code references such as IFGC for gas line work or IPC for potable water systems when selecting ferrule and fitting materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Ferrule\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BD-KP4491\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543465820466,"sku":"BD-KP4491","price":125.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1990a17b5ba100d2e250670e77d68d20.jpg?v=1785919036","url":"https:\/\/voomisupply.com\/products\/parker-bd-kp4491-brass-compression-ferrule-1-4-inch-od-10pk","provider":"Voomi Supply","version":"1.0","type":"link"}
