The larger port measures 1\/2-14 NPTF and the smaller port measures 1\/4-18 NPTF, allowing a direct reduction without additional adapters. At 1.28 inches in length with a 1.06-inch hex, this compact coupling is rated to 1200 psi and handles a temperature range of -65 to 250 degrees F. It is installed by plumbers, HVAC technicians, and pipefitters working on compressed air, hydraulic, fuel, and fluid-transfer lines.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial piping systems where a size reduction between two female-threaded ports is required. Common applications include instrument lines, hydraulic manifolds, compressed air distribution, and fuel-supply piping. The NPTF thread form provides a pressure-tight seal through thread interference, reducing reliance on added sealant. Compatible base materials include brass, bronze, copper, steel, aluminum, and iron pipe, making it a versatile fit across mixed-material systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces 1\/2-14 NPTF female to 1\/4-18 NPTF female in a single fitting\u003c\/li\u003e\n  \u003cli\u003eRated to 1200 psi working pressure\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -65 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion in fluid and gas service\u003c\/li\u003e\n  \u003cli\u003e1.06-inch hex flat allows standard wrench installation\u003c\/li\u003e\n  \u003cli\u003eSAE pattern design consistent with industrial and mobile equipment standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with brass, bronze, copper, steel, aluminum, and iron pipe in systems using NPTF female-threaded connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers, pipefitters, or HVAC technicians following applicable IPC and system-specific pressure codes. Depressurize and drain the line fully before removing or installing any fitting. Use a calibrated torque wrench on the 1.06-inch hex flats and apply thread sealant per the system fluid compatibility requirements, even though NPTF threads are designed for dry-seal service. Inspect threads for damage before assembly and do not over-tighten, which can crack brass fittings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 1\/2 inch Female NPTF (1\/2-14 thread)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/4 inch Female NPTF (1\/4-18 thread)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1200 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -65 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Pipe Materials\u003c\/strong\u003e: Brass, Bronze, Copper, Steel, Aluminum, Iron\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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 23308X4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948887114034,"sku":"23308X4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f55cd7e4c558b51f382b064317431a3.jpg?v=1791675976","url":"https:\/\/voomisupply.com\/products\/midland-industries-23308x4-reducing-pipe-coupling-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
