Built to extra heavy (XH) duty standards and rated for 300 PSI service, this 1\/2 inch union allows technicians to connect and disconnect pipe runs without cutting or threading. The all-iron construction makes it well suited for gas, steam, and high-pressure liquid applications where corrosion resistance and mechanical strength are critical. At 0.51 pounds, it is compact but solid, meeting the durability requirements expected in commercial and industrial piping installations.\u003c\/p\u003e\n\u003cp\u003eThis union is used in residential and commercial gas piping, steam heating systems, and industrial process lines where a serviceable mechanical joint is needed. Licensed plumbers, pipefitters, and HVAC technicians install this fitting where threaded pipe runs require a break point for future maintenance or equipment removal. The extra heavy rating makes it appropriate for higher-pressure service lines where a standard-duty union would not meet system requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtra heavy (XH) duty construction rated for 300 PSI service\u003c\/li\u003e\n  \u003cli\u003eAll-iron body and seats for compatibility with gas, steam, and high-pressure liquid systems\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch pipe size with standard threaded ends\u003c\/li\u003e\n  \u003cli\u003eBlack finish suitable for exposed or concealed iron piping runs\u003c\/li\u003e\n  \u003cli\u003eDomestically sourced fitting for consistent material quality\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install fitting for 1\/2 inch threaded black iron pipe systems, including gas distribution, steam heating, and high-pressure process piping applications.\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 codes, IFGC requirements for gas systems, or ASME B31 standards for pressure piping. Shut off and depressurize the line completely before breaking or making any threaded union connection. Apply appropriate thread sealant or PTFE tape rated for the service fluid on all male threads before assembly. Do not over-tighten the union nut, as iron fittings can crack under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 300 PSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Extra Heavy (XH)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.51 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic\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: 312703804\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51233273250098,"sku":"0312703804","price":78.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307627150.jpg?v=1780095891","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-312703804-all-iron-union-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
