This fitting transitions a 1.5-inch female NPT opening down to a 1-inch male NPT connection. The hex body provides a flat wrench surface for proper torque during installation. Finished in black iron, this bushing is suited for gas piping, compressed air lines, and similar low-pressure piping applications. Licensed plumbers and pipefitters install these fittings as part of threaded iron pipe assemblies in both residential and light commercial settings. The package contains 10 units sold as a set.\u003c\/p\u003e\n\u003cp\u003eThis hex bushing is used in threaded black iron pipe systems where a pipe size reduction is needed at a fitting, valve, or appliance connection. Common install scenarios include gas appliance drops, air compressor manifolds, and industrial piping headers where 1.5-inch to 1-inch transitions are required. The hex body allows standard pipe wrenches or adjustable wrenches to seat the fitting fully without slipping. The black iron finish is compatible with standard black pipe in gas distribution systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces 1.5-inch female NPT to 1-inch male NPT in a single fitting\u003c\/li\u003e\n  \u003cli\u003eHex body provides secure wrench engagement for proper installation\u003c\/li\u003e\n  \u003cli\u003eBlack iron finish matches standard black iron pipe systems\u003c\/li\u003e\n  \u003cli\u003eSold in a 10-unit package for job-lot or multi-point installs\u003c\/li\u003e\n  \u003cli\u003ePackage weight of 4.51 pounds for the 10-unit set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement fitting for standard NPT threaded black iron pipe systems in gas, air, and compatible fluid piping applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC requirements for gas piping applications. Shut off and depressurize the line before installing or replacing any threaded fitting. Apply approved thread sealant or PTFE tape rated for the intended service to male threads before assembly. Do not over-torque the fitting; use the hex body with a proper pipe wrench to achieve a leak-free connection without cracking the fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1.5 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 Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 units per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 4.51 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\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: B K Mueller Industries\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 521-975HC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHLAND","offers":[{"title":"Default Title","offer_id":51560511013170,"sku":"521-975HC","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e56b9d7323b78d24a73165c7b7cd8e1.jpg?v=1786453102","url":"https:\/\/voomisupply.com\/products\/b-k-mueller-521-975hc-black-hex-bushing-1-5x1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
