Fitted with 3\/4-inch FNPTF (Female National Pipe Tapered Fuel) threads on both ends, this coupling joins two male-threaded pipe sections in a straight-line configuration. It carries a maximum working pressure of 1,200 psi and handles temperatures from -65 degrees F to 250 degrees F, making it suitable for a broad range of fluid handling, fuel, and compressed-air applications. Weighing 0.23 pounds, it is a compact, field-ready fitting used by licensed plumbers, pipefitters, and mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and commercial piping installations where a durable, pressure-rated brass fitting is required. Typical applications include fuel lines, hydraulic systems, compressed-air distribution, and general industrial plumbing. The FNPTF thread standard provides a dryseal connection that seals on the threads themselves, reducing reliance on additional sealants in fuel and pneumatic service. The 1-1\/2-inch overall length and 1-1\/4-inch hex size make it compatible with standard pipe wrenches used in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch FNPTF female threads on both ends for a dryseal threaded connection\u003c\/li\u003e\n  \u003cli\u003e1,200 psi maximum working pressure rating suitable for high-pressure fluid service\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -65 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eStraight-body coupling configuration for in-line pipe joining\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance in fuel, water, and air service\u003c\/li\u003e\n  \u003cli\u003eMeets SAE 130138 standards for industrial fitting performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for industrial and commercial piping systems using 3\/4-inch FNPTF threaded connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and IFGC codes. Shut off and depressurize the affected line completely before removing or installing any threaded fitting. FNPTF dryseal threads are engineered to seal on thread engagement, but verify service requirements for your specific fluid media before omitting thread sealant. Use a pipe wrench sized to the 1-1\/4-inch hex to avoid rounding the fitting body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Shape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: FNPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1,200 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -65 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE 130138\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: EATON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3300X12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51543954653490,"sku":"3300X12","price":60.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cb46c83b0f7ee029c0e865cc0cb25ef.jpg?v=1785922497","url":"https:\/\/voomisupply.com\/products\/eaton-3300x12-brass-pipe-coupling-3-4-in-fnptf-1200-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
