This compact brass valve provides positive shutoff in water, hydronic, and light commercial plumbing systems. The full-port ball design delivers low pressure drop across the valve body when fully open. At 1 pound, the valve is lightweight without sacrificing the structural integrity that brass construction provides. Plumbers and pipefitters install this type of valve for isolation duty on branch lines, equipment connections, and service ports.\u003c\/p\u003e\n\u003cp\u003eThis valve is suited for residential and light commercial plumbing applications where a compact, reliable manual shutoff is needed at a 1\/4-inch connection point. Typical installations include gauge isolation, equipment shutoff, and instrument tapping points on hydronic heating systems, water supply lines, and low-pressure gas service where code permits brass valves. The FNPT x FNPT configuration threads directly onto male NPT fittings or nipples without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass body construction for corrosion resistance in potable water and hydronic systems\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections accept standard male NPT threaded pipe and fittings\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch pipe size suits gauge ports, instrument lines, and small branch connections\u003c\/li\u003e\n  \u003cli\u003eManual ball valve operation provides quick quarter-turn open and close\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight design at 1 pound for tight installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation manual ball valve for 1\/4-inch FNPT threaded plumbing and hydronic piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or qualified pipefitters in accordance with IPC and applicable local codes. Shut off supply pressure and depressurize the line before removing any existing valve or fitting. Apply thread sealant tape or compound to the male NPT threads being engaged, not to the valve's female threads. Verify the valve handle position and flow direction before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 x 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: LEGEND VALVE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 101-551NL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEGEND VALVE","offers":[{"title":"Default Title","offer_id":51542478586162,"sku":"101-551NL","price":19.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/496aea907e82cef20c33423412e6c9b3.jpg?v=1785901392","url":"https:\/\/voomisupply.com\/products\/legend-valve-101-551nl-ball-valve-1-4-inch-fnpt-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
