Machined from brass to ASTM-B-453 and ASTM-B16 standards, it provides a rated working pressure of 3500 psi and a total assembled length of 1.42 inches. This fitting is used in instrumentation, HVAC, refrigeration, and fluid control applications where a leak-tight mechanical connection between tubing and a female threaded fitting is required. Licensed plumbers, HVAC technicians, and instrumentation technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis connector suits residential and light commercial installations where copper or compatible soft tubing meets an FNPT port on valves, gauges, manifolds, or equipment panels. Its straight configuration makes it well suited for in-line runs with no directional change needed. The 3500 psi maximum working pressure makes it appropriate for moderate to high-pressure fluid and gas systems within its rated temperature range. Verify tubing material compatibility before installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass construction per ASTM-B-453 and ASTM-B16 for corrosion resistance in fluid and gas service\u003c\/li\u003e\n\u003cli\u003e3500 psi maximum working pressure for demanding system requirements\u003c\/li\u003e\n\u003cli\u003e1\/4 inch compression inlet x FNPT outlet straight configuration\u003c\/li\u003e\n\u003cli\u003eOverall length of 1.42 inches for compact inline installations\u003c\/li\u003e\n\u003cli\u003eCross-referenced to Swagelok part number B-400-7-4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style compression-to-FNPT straight fitting for 1\/4 inch tubing systems requiring a female NPT threaded connection point.

Shut off and depressurize the system completely before disassembling any fittings or tubing. Do not overtighten compression fittings; hand-snug plus the manufacturer-recommended turns is the standard practice for compression joints. Confirm that tubing is cut square, deburred, and fully seated before tightening the compression nut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\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: 1.42 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: 0.1 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: 4-4 GBZ-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539720667442,"sku":"4-4 GBZ-B","price":22.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84e543f351219665e344fd16228bdc59.jpg?v=1785844095","url":"https:\/\/voomisupply.com\/products\/parker-4-4-gbz-b-1-4-inch-compression-x-fnpt-brass-connector","provider":"Voomi Supply","version":"1.0","type":"link"}
