The body is constructed from 316 stainless steel with a polytetrafluoroethylene (PTFE) seal, making it well suited for corrosive media and demanding process environments. It accepts 1\/2 inch FNPT connections on both ends and is rated to a maximum working pressure of 5,000 psi. At 2.76 inches overall length and 4.26 inches overall height, it fits in compact instrument and service manifold installations. The round handle allows controlled manual actuation. This valve is installed by licensed plumbers, pipefitters, and instrumentation technicians.\u003c\/p\u003e\n\u003cp\u003eThe 8F-V12LN-SS is used in industrial, commercial, and process piping applications where tight shutoff and fine flow regulation are required. Typical installations include hydraulic test rigs, chemical process lines, compressed gas headers, and instrument isolation service. The straight-body configuration suits inline runs where minimal space is available. The FNPT x FNPT end connections are compatible with standard NPT-threaded pipe and fittings common across industrial and HVAC hydronic systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316 stainless steel body for corrosion resistance in aggressive media\u003c\/li\u003e\n  \u003cli\u003ePTFE seat seal provides chemical compatibility across a broad range of fluids and gases\u003c\/li\u003e\n  \u003cli\u003eRated to 5,000 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch FNPT x FNPT end connections for standard NPT threaded installations\u003c\/li\u003e\n  \u003cli\u003eRound handle for controlled manual flow adjustment\u003c\/li\u003e\n  \u003cli\u003eCompact straight-body design at 2.76 inches length and 4.26 inches height\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation needle valve for 1\/2 inch NPT threaded piping systems requiring high-pressure straight-pattern flow control with stainless steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pipefitter, plumber, or instrumentation technician in accordance with applicable codes including ASME B31.3 for process piping. Depressurize and isolate the line completely before removing or installing any valve. Apply thread sealant rated for the service pressure and media to the FNPT connections. Do not exceed the rated working pressure of 5,000 psi.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Needle Valve, Straight Pattern\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 5,000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: 316 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.76 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height (OAH)\u003c\/strong\u003e: 4.26 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: Round\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8F-V12LN-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539501351218,"sku":"8F-V12LN-SS","price":403.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec7383876d3a47b49769ba8dd0459387.jpg?v=1785841921","url":"https:\/\/voomisupply.com\/products\/parker-8f-v12ln-ss-needle-valve-1-2-inch-fnpt-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
