It uses female NPT (FNPT) threading on both ends and is rated at 125 lb pressure class, making it suitable for a range of low- to medium-pressure fluid and gas piping applications. Constructed from brass with a rough finish, this coupling offers reliable corrosion resistance in water, compressed air, and compatible fluid systems. It fits a 3\/4 inch nominal pipe size. Licensed plumbers and pipefitters are the typical installers for this type of fitting in commercial and residential piping systems.\u003c\/p\u003e\n\u003cp\u003eThis coupling is appropriate for use in residential and light commercial plumbing, compressed air distribution, and hydronic heating systems where a 3\/4 inch threaded brass fitting is required. The 125 lb pressure rating fits standard service conditions encountered in typical building utility piping. Its straight configuration makes it a straightforward solution for inline pipe connections where no directional change is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch nominal pipe size for common residential and commercial piping runs\u003c\/li\u003e\n  \u003cli\u003eFNPT threading on both ends for standard threaded pipe connections\u003c\/li\u003e\n  \u003cli\u003e125 lb pressure class rating suitable for low- to medium-pressure service\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance in water and compatible fluid applications\u003c\/li\u003e\n  \u003cli\u003eRough finish — compatible with pipe dope or PTFE tape sealing\u003c\/li\u003e\n  \u003cli\u003eStraight coupling design for inline pipe joining without directional change\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 3\/4 inch NPT threaded pipe systems operating within a 125 lb pressure class service rating.\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 local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the piping system before removing or installing any threaded fittings. Apply PTFE tape or an approved pipe thread sealant to the male threads before making up the joint. Do not over-tighten, as brass threads can be damaged by excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Pipe Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Thread) both ends\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 125 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Rough\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Straight coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Import\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: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: XNL111-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51524429840690,"sku":"COUP34LF","price":15.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40a6096ecaa7eb7d500657da416438fe_23cf359a-9cee-4198-8127-a5c314fd6812.jpg?v=1785448952","url":"https:\/\/voomisupply.com\/products\/merit-brass-xnl111-12-3-4-inch-fnpt-straight-pipe-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
