This fitting accepts a larger female thread on one end and a smaller male thread on the other, allowing technicians to connect pipes or fittings of different nominal sizes within the same run. The black finish is standard for gas distribution applications. Each unit ships as part of a 5-pack, making it practical for service vehicles and job-site stock. Licensed plumbers and pipefitters are the primary installers of this type of fitting.\u003c\/p\u003e\u003cp\u003eBlack hex bushings in this size range are commonly used in residential and light commercial gas piping systems, as well as in some hydronic and industrial plumbing applications. The 2-inch female to 1-inch male configuration is a frequently encountered reduction in gas branch lines, manifold assemblies, and equipment connections where pipe sizes transition at valves, meters, or appliance inlets.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-inch female NPT to 1-inch male NPT reduction in a single fitting\u003c\/li\u003e\n\u003cli\u003eBlack finish suits gas piping and iron pipe system applications\u003c\/li\u003e\n\u003cli\u003eHex profile allows secure wrench engagement during installation\u003c\/li\u003e\n\u003cli\u003eSold in a 5-pack quantity for job-site or service-truck stocking\u003c\/li\u003e\n\u003cli\u003eCompact hex bushing design reduces the need for additional coupling and nipple combinations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-stock fitting for black iron pipe systems using NPT threaded connections in residential and commercial gas or plumbing installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of black hex bushings in gas piping systems must be performed by a licensed plumber or gas fitter in accordance with the International Fuel Gas Code (IFGC) and applicable local codes. Shut off and verify zero pressure at the gas supply before threading any fitting. Apply appropriate thread sealant or listed pipe compound rated for gas service to the male threads before assembly. Do not use excessive force or extensions on the wrench, as overtightening can crack or distort the fitting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 2 inches (female NPT)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1 inch (male NPT)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: B K\/MUELLER INDS(IMPORT)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 521-985HN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHLAND","offers":[{"title":"Default Title","offer_id":51558889554226,"sku":"521-985HN","price":25.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7cc4cd83f1e703a58e22f20573e9868c.jpg?v=1786421907","url":"https:\/\/voomisupply.com\/products\/b-k-mueller-indsimport-521-985hn-black-hex-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
