It features a compression inlet on one end and a 1\/8 inch MNPT threaded outlet on the other, creating a reliable, leak-resistant connection without soldering or flaring. Rated to 3500 psi maximum working pressure, this fitting is built to ASTM-B-453 and ASTM-B16 standards, making it suitable for high-pressure hydraulic, pneumatic, refrigeration, and instrumentation lines. Licensed HVAC technicians, plumbers, and instrumentation mechanics commonly install this fitting in control and sensing line applications.\u003c\/p\u003e\u003cp\u003eThis connector is used in residential and commercial settings wherever a compression tube must transition to an NPT threaded port. Typical applications include refrigerant sensing lines, hydraulic instrument tubing, pneumatic control circuits, and gas sampling lines. Its straight configuration keeps the connection compact and inline, which is useful in confined spaces or panel-mounted components. The 1.29 inch overall length keeps the fitting footprint small for tight installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3500 psi maximum working pressure for demanding hydraulic and pneumatic service\u003c\/li\u003e\n\u003cli\u003eCompression x MNPT end connections eliminate soldering and flaring\u003c\/li\u003e\n\u003cli\u003eStraight fitting shape for direct inline tube-to-port connections\u003c\/li\u003e\n\u003cli\u003eBrass construction conforming to ASTM-B-453 and ASTM-B16 standards\u003c\/li\u003e\n\u003cli\u003e1\/8 inch MPT thread size compatible with standard NPT ported components\u003c\/li\u003e\n\u003cli\u003eCompact 1.29 inch overall length suits confined installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation compression connector for systems requiring a 1\/8 inch MNPT threaded port connection to compression tubing.

Depressurize and isolate the line completely before removing or installing any compression fitting. Hand-tighten the compression nut onto the tube, then advance with a wrench per the fitting manufacturer's recommended turns — do not overtighten, as brass compression fittings can crack or deform the ferrule. Apply thread sealant compatible with the service fluid on the MNPT threads, and verify for leaks at operating 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: 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 MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: MPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Shape\u003c\/strong\u003e: Straight\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: 1.29 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM-B-453, ASTM-B16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 4-2 FBZ-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542277292338,"sku":"4-2 FBZ-B","price":19.14,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1f82e8303122cb4b38c8adf9dfabce2.jpg?v=1785897121","url":"https:\/\/voomisupply.com\/products\/parker-4-2-fbz-b-compression-tube-connector-1-8-inch-mnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
