It uses female NPT (FNPT) threads on both ends for a standard tapered-thread connection. Rated to 125 lb pressure class, it is constructed from brass with a rough finish. This type of fitting is installed by licensed plumbers and pipefitters working on water, fuel gas, or other compatible fluid systems where a reliable, threaded inline connection is required.\u003c\/p\u003e\u003cp\u003eThe XNL111-24 is suited for residential and light commercial plumbing and piping applications. The 1-1\/2 inch nominal size makes it a common fit for water supply lines, drain and vent rough-in work, and low-pressure gas distribution piping. The FNPT thread form is compatible with standard NPT male-threaded pipe and fittings, making this coupling straightforward to source and replace in the field.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStraight coupling design joins two pipe sections in a direct, inline configuration\u003c\/li\u003e\n\u003cli\u003eFNPT (female NPT) threads on both ends accept standard tapered male pipe threads\u003c\/li\u003e\n\u003cli\u003e125 lb pressure class rating for low- to medium-pressure service\u003c\/li\u003e\n\u003cli\u003eBrass construction provides corrosion resistance suitable for water and compatible fluid service\u003c\/li\u003e\n\u003cli\u003e1-1\/2 inch nominal size fits standard Schedule 40 and Schedule 80 pipe of the same nominal diameter\u003c\/li\u003e\n\u003cli\u003eRough finish — no additional plating or coating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-stock fitting for threaded pipe systems using 1-1\/2 inch nominal NPT connections in plumbing, HVAC hydronic, or low-pressure gas piping applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements for the fluid service. Apply an approved thread sealant or PTFE tape to the male threads before making up the joint — do not apply sealant to female threads. Hand-tighten first, then wrench-tighten to avoid cross-threading. Shut off and depressurize the line completely before removing any existing fitting or cutting into an existing system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female NPT) both ends\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\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\u003eCoupling Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: XNL111-24\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51524759388466,"sku":"COUP112LF","price":34.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40a6096ecaa7eb7d500657da416438fe_a19ba1a8-23c4-48b0-b593-3941ff49bd58.jpg?v=1785456991","url":"https:\/\/voomisupply.com\/products\/merit-brass-xnl111-24-straight-pipe-coupling-1-1-2-in-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
