This standard threaded fitting connects pipe to pipe without a change in direction or diameter, making it a staple component in water, oil, air, and gas distribution lines. Plumbers and pipefitters reach for merchant couplings when a full-length standard coupling is not required, as the shorter body reduces overall assembly length. The malleable iron construction provides adequate strength and ductility for typical low-pressure service conditions.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial piping applications where low-pressure service is the norm. Common install scenarios include water supply lines, compressed air distribution, fuel oil runs, and low-pressure gas piping. The black iron finish is standard for gas line work in both residential and commercial settings. Pipefitters and plumbers install this fitting in new construction and retrofit work alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/8 inch pipe size for small-diameter low-pressure runs\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides ductility and resistance to cracking under stress\u003c\/li\u003e\n  \u003cli\u003eBlack iron finish suited for gas, oil, water, and air service\u003c\/li\u003e\n  \u003cli\u003eMerchant-style body is shorter than a standard coupling, reducing assembly length\u003c\/li\u003e\n  \u003cli\u003eThreaded ends connect straight pipe to straight pipe without change in direction\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\/8 inch NPT threaded black iron pipe systems in low-pressure water, oil, air, and gas service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable code requirements, including IFGC guidelines for gas piping. Shut off the gas, water, or air supply and relieve system pressure before breaking into any existing line. Apply an approved thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded fittings on malleable iron, as the material, while ductile, can crack under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable black iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Merchant coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded (NPT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.037 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\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: 8700157905\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51347943457074,"sku":"8700157905","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547614.jpg?v=1782116453","url":"https:\/\/voomisupply.com\/products\/asc-8700157905-black-iron-merchant-coupling-1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
