Ground joint unions use a precision-machined metal-to-metal seat at the center nut to create a leak-resistant connection without a gasket. This fitting is used to join two sections of threaded pipe and allow disconnection for service or replacement without disturbing the rest of the run. Licensed plumbers and pipefitters install these fittings on gas, steam, and low-pressure air systems where a reliable, reusable threaded connection is required.\u003c\/p\u003e\n\u003cp\u003eThis union is suited for residential and light commercial applications involving black iron pipe systems. Typical installations include natural gas branch lines, steam heating distribution, and compressed air drops where a serviceable connection point is needed. The black coating is standard for gas piping applications. At 0.48 pounds, this 1\/4 inch fitting is appropriate for small-diameter branch connections and instrumentation tie-ins on iron pipe systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGround joint metal-to-metal seat — no gasket required for a tight seal\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch fitting size for small-diameter iron pipe connections\u003c\/li\u003e\n  \u003cli\u003e150 PSI pressure rating for gas, steam, and air service\u003c\/li\u003e\n  \u003cli\u003eBlack iron construction with black coating for standard gas piping applications\u003c\/li\u003e\n  \u003cli\u003eDomestically produced fitting\u003c\/li\u003e\n  \u003cli\u003eReusable union design allows line disconnection without cutting pipe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 1\/4 inch NPT black iron pipe systems rated at 150 PSI.\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 and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where applicable. Shut off and depressurize the line before disassembling or installing any union fitting. Apply appropriate thread sealant to the male NPT threads on both end connections, but keep sealant off the ground joint seat faces. Hand-tighten the union nut to align the seat, then wrench-tighten to achieve a leak-free joint without overloading the fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Material\u003c\/strong\u003e: Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Ground Joint\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.48 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\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: 312822026\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51233518387506,"sku":"0312822026","price":108.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307627151.jpg?v=1780102031","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-312822026-black-iron-union-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
