It features a round handle, a brass body, and a polytetrafluoroethylene (PTFE) seal for chemical resistance and low-friction operation. Connections are 3\/8-inch female NPT (FNPT) on both ends. The valve is rated for a maximum working pressure of 3,000 psi, making it suitable for demanding industrial and commercial service applications. Overall assembled length is 2.68 inches and overall assembled height is 4.18 inches. This type of valve is typically installed by licensed plumbers, pipefitters, or HVAC technicians working on high-pressure fluid or gas lines.\u003c\/p\u003e\n\u003cp\u003eThis valve is suited for straight-run installations in systems requiring fine throttling or shutoff control. The 3\/8-inch FNPT x FNPT configuration integrates directly into threaded pipe runs without additional adapters. Its brass body and PTFE seal make it a practical choice for water, oil, air, and compatible fluid services in both light commercial and industrial settings. It ships individually and has a minimum order quantity of one unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStraight-body configuration for in-line installation in threaded pipe runs\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch FNPT x FNPT connections on both ends for direct threaded integration\u003c\/li\u003e\n  \u003cli\u003eBrass body construction for corrosion resistance in plumbing and fluid service\u003c\/li\u003e\n  \u003cli\u003ePTFE seal provides chemical compatibility and reliable low-friction sealing\u003c\/li\u003e\n  \u003cli\u003eRated to 3,000 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eRound handle for manual flow control and easy operation in tight 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 needle valve for 3\/8-inch threaded pipe systems requiring FNPT x FNPT straight-pattern valves in high-pressure service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pipefitter, plumber, or HVAC technician familiar with high-pressure threaded connections. Depressurize and isolate the line completely before removing or installing any valve. Apply thread sealant appropriate for the service fluid to the male NPT threads being engaged. Verify the system pressure does not exceed the 3,000 psi rated limit of this valve before returning the line to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 3,000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.68 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height (OAH)\u003c\/strong\u003e: 4.18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 6F-V8LN-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540575912242,"sku":"6F-V8LN-B","price":366.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/988cc9118329dcee639617960fb3e8eb.jpg?v=1785858895","url":"https:\/\/voomisupply.com\/products\/parker-6f-v8ln-b-needle-valve-3-8-inch-fnpt-brass-3000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
