The bushing reduces from a 3\/8-inch female thread to a 1\/4-inch male thread, making it a compact solution for transitioning between pipe sizes in a single fitting. Constructed in black-finish iron, it is suited for use in low-pressure piping systems carrying fuel gases, LP gas, lubricating oils, greases, and similar non-potable fluids. Licensed plumbers, gas fitters, and pipefitters install this type of fitting as part of standard threaded pipe assemblies. It is not rated or approved for potable water service.\u003c\/p\u003e\n\u003cp\u003eThis hex bushing sees common use in residential and light commercial piping applications where a threaded pipe size change is needed in a tight space. The hex profile allows a wrench to grip and tighten the fitting without requiring additional tools. Typical applications include fuel oil lines, LP gas distribution piping, lubrication systems, and similar fluid-transport setups. It is also frequently used in small fabrication and repair projects involving standard NPT threaded iron pipe.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces 3\/8-inch female NPT to 1\/4-inch male NPT in a single fitting\u003c\/li\u003e\n  \u003cli\u003eBlack iron construction suitable for fuel gas and oil service\u003c\/li\u003e\n  \u003cli\u003eHex body profile allows standard wrench installation\u003c\/li\u003e\n  \u003cli\u003eNot approved for potable water applications\u003c\/li\u003e\n  \u003cli\u003eSold individually, one fitting per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard NPT threaded hex bushing for use in iron pipe systems transporting fuel gases, LP gas, lubricating oils, and greases.

Shut off and depressurize the piping system fully before installing or removing any threaded fitting. Apply appropriate thread sealant or PTFE tape rated for the intended service medium before making up the joint. Do not overtighten; use the hex profile with a properly sized wrench to achieve a leak-free connection without cracking the fitting body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Thread Size\u003c\/strong\u003e: 3\/8 inch female NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Thread Size\u003c\/strong\u003e: 1\/4 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\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePotable Water Rated\u003c\/strong\u003e: No\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: SOUTHLAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 521-921HN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHLAND","offers":[{"title":"Default Title","offer_id":51786840277298,"sku":"521-921HN","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8935c0e676f387c3b5f587257819ec1a_b1b3474f-4419-4a3f-a04e-26e0879126d5.jpg?v=1789207150","url":"https:\/\/voomisupply.com\/products\/southland-521-921hn-black-hex-bushing-3-8x1-4-pipe-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
