Manufactured from brass conforming to ASTM-B-124 and BS2872 standards, this fitting connects a compression tube end to a female NPT threaded port at a right angle. It carries a maximum working pressure of 3500 psi, making it suitable for demanding instrumentation, pneumatic, and hydraulic applications. Licensed HVAC technicians, plumbers, and instrumentation mechanics install this fitting where a direction change is needed between a compression tube run and a female-threaded port on valves, manifolds, or equipment panels.\u003c\/p\u003e\n\u003cp\u003eThis fitting is commonly used in residential and commercial HVAC refrigerant line instrumentation, compressed air systems, hydraulic control lines, and process piping wherever a 90-degree transition from compression tubing to a 1\/4 inch female NPT port is required. Its compact elbow profile keeps installations tight in panel enclosures and equipment cabinets. The all-brass construction resists corrosion in both wet and dry service environments, and the FNPT end accepts standard pipe thread connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree elbow geometry routes tubing at a right angle with a single fitting\u003c\/li\u003e\n  \u003cli\u003e3500 psi maximum working pressure for high-pressure instrumentation and control line service\u003c\/li\u003e\n  \u003cli\u003eBrass construction per ASTM-B-124 and BS2872 for corrosion resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eCompression x FNPT end connections allow tubing-to-pipe-thread transitions without soldering or brazing\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch thread size fits standard NPT female ports on valves, manifolds, and equipment fittings\u003c\/li\u003e\n  \u003cli\u003eCross-referenced as Swagelok part number B-400-8-4 for compatibility verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression fitting for instrumentation, pneumatic, hydraulic, and fluid control systems requiring a 1\/4 inch female NPT port connection.

Shut off and depressurize the system fully before removing or installing any compression fitting. Compression fittings do not require thread sealant on the compression end, but apply an appropriate thread sealant or tape to the NPT threads per local plumbing or mechanical codes. Do not overtighten the compression nut, as over-compression can deform the ferrule and compromise the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Female Elbow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Shape\u003c\/strong\u003e: 90 Degree Elbow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Compression x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: FPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 3500 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM-B-124, BS2872\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\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: 4FEL4N-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542744138034,"sku":"4FEL4N-B","price":30.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b3d95f57d83cc599b39e08f4b18d58e_bd02e32f-548b-4a6c-b4bb-34475cb9d63d.jpg?v=1785905974","url":"https:\/\/voomisupply.com\/products\/parker-4fel4n-b-compression-female-elbow-1-4-inch-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
