It features female National Pipe Taper (FNPT) ends on both sides and a 125 lb pressure rating, making it suitable for a wide range of low-to-medium pressure fluid and gas distribution systems. Constructed from rough brass, it offers solid corrosion resistance for use in plumbing and mechanical piping applications. The 1-1\/4 inch nominal pipe size fits standard Schedule 40 pipe threads. Licensed plumbers and pipefitters are the typical installers for this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThis coupling is commonly used in residential and light commercial plumbing, hydronic heating systems, compressed air lines, and gas distribution piping where a straight, in-line pipe connection is required. The 1-1\/4 inch nominal size is frequently encountered in supply mains, branch runouts, and equipment connections. Its brass construction makes it well suited for installations where dezincification-resistant or copper-compatible fittings are preferred over iron or steel alternatives.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4 inch nominal pipe size for standard Schedule 40 threaded connections\u003c\/li\u003e\n  \u003cli\u003eFNPT ends on both sides for straight in-line pipe joining\u003c\/li\u003e\n  \u003cli\u003e125 lb pressure-rated brass construction\u003c\/li\u003e\n  \u003cli\u003eRough brass finish suitable for soldering or direct installation\u003c\/li\u003e\n  \u003cli\u003eCompact straight coupling profile with no center stop, allowing full makeup\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 compatible with 1-1\/4 inch NPT threaded pipe systems in standard plumbing and mechanical piping applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local codes. Always shut off and depressurize the supply line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to male threads before makeup, and hand-tighten before applying wrench torque. Do not over-torque brass fittings, as the material is more susceptible to thread damage than iron or steel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Pipe Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Taper) 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\u003eFitting Type\u003c\/strong\u003e: Straight Pipe 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: XNL111-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51523976331570,"sku":"COUP114LF","price":27.12,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40a6096ecaa7eb7d500657da416438fe.jpg?v=1785444607","url":"https:\/\/voomisupply.com\/products\/merit-brass-xnl111-20-straight-pipe-coupling-1-1-4-in-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
