Both ends accept 3\/4-inch female NPTF connections, rated to 1000 psi working pressure. The union is machined from solid brass barstock, which provides tighter dimensional tolerances and better pressure integrity than cast alternatives. Operating temperature range spans -65 to 250 degrees F, making it suitable for a broad range of fluid and gas service applications. Licensed plumbers and pipefitters install this fitting in commercial and residential systems where future serviceability of the line is required.\u003c\/p\u003e\u003cp\u003eThis union is used in plumbing, hydronic heating, compressed air, and light industrial piping systems where 3\/4-inch threaded pipe is present. The female NPTF thread form creates a pressure-tight dry seal without relying solely on thread sealant, reducing leak risk in high-cycle or high-pressure service. It is well suited for mechanical rooms, utility installations, and retrofit work where an existing pipe run must be broken for equipment service or replacement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1000 psi working pressure rating for demanding service conditions\u003c\/li\u003e\n\u003cli\u003eBoth ends: 3\/4-inch female NPTF for pressure-tight dry-seal threading\u003c\/li\u003e\n\u003cli\u003eMachined from brass barstock for close tolerances and reliable pressure integrity\u003c\/li\u003e\n\u003cli\u003eWide temperature range: -65 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003e1.68-inch hex for standard wrench engagement\u003c\/li\u003e\n\u003cli\u003eCompact body length of 1.96 inches suits tight installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 3\/4-inch female NPTF threaded pipe systems in plumbing, hydronic, and compressed-air applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters in accordance with applicable IPC and local plumbing code requirements. Shut off and depressurize the system completely before disassembly or installation. Use an appropriate thread sealant or PTFE tape on mating male threads even with NPTF connections to ensure long-term joint integrity. Use a properly sized wrench on the 1.68-inch hex flats  -  do not use pipe wrenches on the body, as they can deform the fitting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Female NPTF x Female NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Pressure\u003c\/strong\u003e: 1000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -65 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1.68 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.96 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.65 inches\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: 0.495 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: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 28071\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67950708392242,"sku":"28071","price":53.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2dfb3310b5d4d987b570f9b02e921432_b48d0e6c-17a5-46fb-bb65-382b674d0c8f.jpg?v=1791723221","url":"https:\/\/voomisupply.com\/products\/midland-industries-28071-brass-pipe-union-3-4-in-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
