Parker 6F-V8LN-B Needle Valve 3/8 Inch Fnpt Brass 3000 Psi

Product Description

The PARKER 6F-V8LN-B is a straight needle valve designed for precise flow control in hydraulic and pneumatic plumbing systems. 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.

This 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.

Key Features

• Straight-body configuration for in-line installation in threaded pipe runs
• 3/8-inch FNPT x FNPT connections on both ends for direct threaded integration
• Brass body construction for corrosion resistance in plumbing and fluid service
• PTFE seal provides chemical compatibility and reliable low-friction sealing
• Rated to 3,000 psi maximum working pressure
• Round handle for manual flow control and easy operation in tight spaces

Compatibility

Designed 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.

Installation Notes

Installation 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.
