It features a round handle for manual operation and a brass body with a polytetrafluoroethylene (PTFE) seal that provides reliable shutoff and chemical resistance across a wide range of media. Rated to 3,000 psi maximum working pressure, this valve is built for demanding service environments. Female NPT connections on both ends allow for straightforward inline installation. With an overall length of 1.88 inches and an overall height of 3.55 inches, it fits compact installations where space is a consideration. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis needle valve is suited for residential and light commercial applications where accurate flow throttling or shutoff is required. Common use cases include instrument tubing, refrigeration and HVAC line control, pneumatic systems, hydraulic circuits, and general plumbing service lines carrying compatible fluids or gases. The FNPT x FNPT straight configuration makes it a standard inline fitting for 1\/4 inch pipe systems. Its compact body size is well matched to instrument-grade and OEM panel applications where a small footprint is essential.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStraight-pattern body with round handle for manual, incremental flow control\u003c\/li\u003e\n  \u003cli\u003eBrass body construction offers corrosion resistance for water, oil, and many industrial media\u003c\/li\u003e\n  \u003cli\u003ePTFE seat and seal provide chemical compatibility and low-friction operation\u003c\/li\u003e\n  \u003cli\u003eRated to 3,000 psi maximum working pressure for high-pressure service\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch FNPT x FNPT end connections for direct inline pipe installation\u003c\/li\u003e\n  \u003cli\u003eCompact overall dimensions: 1.88 inches OAL, 3.55 inches OAH\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard OEM-style inline needle valve for 1\/4 inch female NPT pipe systems in HVAC, refrigeration, instrumentation, pneumatic, and hydraulic applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable codes including IFGC and IPC where relevant. Depressurize and isolate the line completely before removing any existing valve or fitting. Apply thread sealant compatible with the system media to the male NPT threads being engaged; do not apply sealant to the first one or two threads. Verify that flow direction and pressure rating are appropriate for the system 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\u003ePipe Size\u003c\/strong\u003e: 1\/4 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\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\u003eMaximum Working Pressure\u003c\/strong\u003e: 3,000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height (OAH)\u003c\/strong\u003e: 3.55 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\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: 4F-V6LN-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542872228146,"sku":"4F-V6LN-B","price":270.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff8ef4194e69b78b5db4cdb3cdd6a11d.jpg?v=1785909465","url":"https:\/\/voomisupply.com\/products\/parker-4f-v6ln-b-needle-valve-1-4-inch-fnpt-brass-3000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
