Rated Class 150, this union is manufactured to ANSI B-16.39 dimensional and performance standards and is intended for joining and disconnecting threaded pipe runs without disturbing the rest of the system. Licensed plumbers and pipefitters install this fitting in water supply, low-pressure steam, air, and gas distribution systems where a serviceable break point is needed. The malleable iron construction provides greater ductility and impact resistance than cast iron in the same application.\u003c\/p\u003e\n\u003cp\u003eThis union is suited for residential and light commercial plumbing and mechanical piping systems. It is a direct threaded connection on both ends using standard NPT taper threads per ANSI B-2.1, making it compatible with standard Schedule 40 threaded pipe. Typical install scenarios include boiler supply and return piping, compressed air drops, and gas branch lines where periodic disconnection for service is anticipated. The galvanized finish extends service life in damp or outdoor-adjacent environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass 150 pressure rating per ANSI B-16.39\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch FPT connection on both ends using ANSI B-2.1 NPT taper threads\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish provides corrosion resistance in damp service environments\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction offers greater ductility than standard cast iron fittings\u003c\/li\u003e\n  \u003cli\u003eMeets Federal Specification WW-U-531C and ANSI B-16.39 for malleable iron unions\u003c\/li\u003e\n  \u003cli\u003eAllows pipe disconnection without disturbing adjacent fittings or pipe runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded union for use with standard 3\/4-inch Schedule 40 threaded pipe in Class 150 malleable iron piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the pipe system completely before disassembly or installation. Apply thread sealant or PTFE tape to NPT threads before makeup; do not overtighten, as malleable iron threads can crack under excessive torque. Verify that the galvanized fitting is compatible with any pipe dope or sealant used, particularly on gas service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/4 inches FPT x 3\/4 inches FPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: ANSI B-2.1 NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: Class 150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.63 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI B-16.39, ANSI B-16.14, Federal Specification WW-U-531C, Federal Specification WW-P-471-B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00690291034114\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: ASC ENGINEERED SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8700163457\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51342944305458,"sku":"8700163457","price":24.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547669.jpg?v=1782011447","url":"https:\/\/voomisupply.com\/products\/asc-8700163457-3-4-in-fpt-malleable-iron-galvanized-union","provider":"Voomi Supply","version":"1.0","type":"link"}
