Built from solid brass, this coupler features a 3\/4 inch body diameter with threaded connection to provide a secure, leak-resistant joint under repeated connect and disconnect cycles. The 1-11\/2 NPTF thread form creates a pressure-tight seal on the threads themselves, reducing reliance on additional sealant compounds. Weighing 1.24 pounds, it is suited for stationary and portable pneumatic tool hookups in industrial and commercial environments. Licensed HVAC technicians, pipefitters, and maintenance mechanics working with pneumatic lines are the primary installers of this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThis coupler is appropriate for use in industrial plant air systems, maintenance shop compressed air lines, and general-purpose pneumatic tool circuits where a dependable threaded female inlet connection is required. The brass construction makes it compatible with a wide range of compressed air and inert gas service applications where corrosion resistance and machinability of the connection point are priorities. It is intended for installations where the mating male plug follows the standard industrial interchange coupler body style.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch coupler body diameter for high-flow pneumatic service\u003c\/li\u003e\n  \u003cli\u003eFemale NPTF threaded connection provides a pressure-tight seal at the thread interface\u003c\/li\u003e\n  \u003cli\u003eSolid brass construction offers corrosion resistance for air and inert gas lines\u003c\/li\u003e\n  \u003cli\u003eIndustrial interchange coupler style for broad compatibility with standard male plugs\u003c\/li\u003e\n  \u003cli\u003eCompact, single-unit package ready for immediate installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct installation fitting for industrial pneumatic systems using standard 1-11\/2 female NPTF threaded coupler connections with a 3\/4 inch body diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pipefitter or maintenance mechanic following applicable compressed air system safety procedures. Depressurize and bleed down the pneumatic line completely before removing or installing any coupler. Apply thread sealant tape or compound appropriate for pneumatic service to the male threads before engagement, and tighten to the fitting manufacturer recommended range using a properly sized open-end or pipe wrench. Verify the system is leak-free at operating pressure before returning to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupler Size\u003c\/strong\u003e: 3\/4 inch body diameter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Female NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-11\/2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.24 pounds\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: B39J\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540650230066,"sku":"B39J","price":196.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4564f1969c536b999195d5401a5bda98.jpg?v=1785860869","url":"https:\/\/voomisupply.com\/products\/parker-b39j-female-nptf-pneumatic-hose-coupler-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
