Built from brass conforming to ASTM-B-453 and ASTM-B16 standards, this fitting handles up to 3500 psi working pressure, making it suitable for hydraulic, pneumatic, and fluid-handling lines in HVAC, plumbing, and industrial service applications. The compression-to-MNPT configuration allows a technician to transition from soft copper or brass tubing directly into a threaded port without soldering or brazing. At 1.51 inches overall length and 0.1 pounds, it is a compact, field-ready fitting stocked for single-unit installation needs.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial mechanical systems where a reliable, leak-resistant connection between compression tubing and a male pipe thread is required. Typical applications include refrigerant line accessories, water supply connections, instrumentation lines, and control tubing runs. HVAC technicians, plumbers, and pipefitters commonly install this fitting when transitioning tubing into valve bodies, gauges, or threaded manifold ports. The straight body geometry makes it well suited to inline runs with no directional change required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompression x MNPT end connections allow direct tubing-to-pipe-thread transition without soldering\u003c\/li\u003e\n  \u003cli\u003e3500 psi maximum working pressure rated for demanding hydraulic and pneumatic service\u003c\/li\u003e\n  \u003cli\u003eBrass construction meets ASTM-B-453 and ASTM-B16 material standards\u003c\/li\u003e\n  \u003cli\u003eStraight fitting shape supports clean inline installations\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch thread size with MPT thread standard\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1.51 inches for use in tight installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression-to-MNPT brass fitting for use in residential and commercial fluid and gas handling systems requiring a 3\/8 inch male pipe thread connection.

Shut off and depressurize the system fully before removing or installing any compression fitting. Use a calibrated torque wrench and follow the fitting manufacturer's ferrule-seating procedure — do not over-tighten, as brass compression fittings can deform the ferrule and cause leaks. Inspect the tubing end for squareness and deburr before inserting into the compression nut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 3\/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: 1.51 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM-B-453, ASTM-B16\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: 4-6 FBZ-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542528557362,"sku":"4-6 FBZ-B","price":23.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b80f4843f022dae9ab495452d548554b.jpg?v=1785902921","url":"https:\/\/voomisupply.com\/products\/parker-4-6-fbz-b-compression-tube-connector-3-8-inch-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
