It accepts a compression tube connection on one end and a female NPT threaded connection on the other. Rated to a maximum working pressure of 3500 psi, this fitting is well-suited for demanding fluid and instrumentation systems. The brass construction meets ASME-SB75 and ASTM-B75 standards, confirming material traceability and quality for trade and industrial applications. Licensed plumbers, instrumentation technicians, and mechanical contractors typically install this type of fitting.\u003c\/p\u003e\u003cp\u003eThis fitting is appropriate for use in HVAC, refrigeration, pneumatic, and instrumentation plumbing systems where tubing must pass through a panel or wall partition. The compression-by-FNPT configuration allows connection to standard female pipe-threaded ports on valves, manifolds, or equipment housings on one side, and a compression tube on the other. It is suited for both light commercial and industrial installations where high-pressure integrity and a compact through-wall connection are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBulkhead design allows tubing to pass cleanly through a panel or wall\u003c\/li\u003e\n\u003cli\u003eCompression x FNPT end connections for versatile system integration\u003c\/li\u003e\n\u003cli\u003eMaximum working pressure of 3500 psi for high-pressure service\u003c\/li\u003e\n\u003cli\u003eBrass construction conforming to ASME-SB75 and ASTM-B75 material standards\u003c\/li\u003e\n\u003cli\u003e1\/4 inch thread size with FPT thread standard\u003c\/li\u003e\n\u003cli\u003eOverall length of 2.04 inches for compact panel installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCross-references to Swagelok part number B-400-71-4.

Depressurize and isolate the system completely before removing or installing any fitting. Follow the fitting manufacturer's recommended tube preparation and ferrule seating procedure — do not overtighten, as brass compression fittings can be damaged by excessive torque. Verify all connections are leak-free under system pressure before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Bulkhead Female Connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\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\u003eMaximum Working Pressure\u003c\/strong\u003e: 3500 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME-SB75, ASTM-B75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwagelok Cross Reference\u003c\/strong\u003e: B-400-71-4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 4FBC4N-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542817341746,"sku":"4FBC4N-B","price":173.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e8d1391b5052ae0ca87ad7dca8b614a.jpg?v=1785908233","url":"https:\/\/voomisupply.com\/products\/parker-4fbc4n-b-bulkhead-female-connector-1-4-in-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
