It joins a compression tube end to a 1\/8 inch FNPT port in a single inline fitting. Rated to 3500 psi maximum working pressure and manufactured to ASTM-B-453 and ASTM-B16 standards, this connector is suited for instrument, pneumatic, and hydraulic tubing runs where a leak-tight mechanical connection to a female threaded port is required. Licensed plumbers, HVAC technicians, and instrumentation mechanics are the typical installers. Overall length is 1.23 inches and the unit weighs 0.06 pounds.\u003c\/p\u003e\u003cp\u003eThis fitting is used in residential and commercial applications wherever small-bore tubing must terminate at a female pipe thread port. Common install scenarios include instrument sensing lines, pressure gauge connections, refrigeration service ports, and pneumatic control circuits. The straight body keeps the tubing run aligned with the port axis, reducing stress on the tubing wall in tight panel or equipment enclosures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3500 psi maximum working pressure for high-integrity tube connections\u003c\/li\u003e\n\u003cli\u003eCompression x FNPT end connections allow tool-free tube insertion with threaded port engagement\u003c\/li\u003e\n\u003cli\u003eBrass construction per ASTM-B-453 and ASTM-B16 for corrosion resistance in wet and pneumatic service\u003c\/li\u003e\n\u003cli\u003eStraight fitting shape minimizes installation space and tubing stress\u003c\/li\u003e\n\u003cli\u003e1\/8 inch thread size fits common instrument and control port sizes\u003c\/li\u003e\n\u003cli\u003eCompact 1.23 inch overall length suits confined enclosures and equipment panels\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation straight compression connector for 1\/8 inch FNPT female pipe thread ports in instrumentation, pneumatic, and fluid-handling systems.

Depressurize and isolate the tubing circuit completely before disassembling or installing any compression fitting. Hand-tighten the compression nut onto the FNPT port, then advance with a wrench per the fitting manufacturer fitting-up procedure for compression fittings. Do not over-tighten the compression nut, as this can deform the ferrule and compromise the seal.\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 FNPT\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: FPT\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: 1.23 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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\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 GBZ-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542436675890,"sku":"4-2 GBZ-B","price":24.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ba58195a91f0feb99e42e31abd95354_f17b0849-bb5a-4fde-beb1-bb96798e2cfb.jpg?v=1785900449","url":"https:\/\/voomisupply.com\/products\/parker-4-2-gbz-b-compression-tube-connector-1-8-inch-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
