Parker 6M-V6LN-B Needle Valve 3/8 Inch Mnpt Brass

Product Description

The PARKER 6M-V6LN-B is a straight needle valve designed for precise flow control in pressurized fluid and gas systems. It features a round handle, a brass body, and a polytetrafluoroethylene (PTFE) seal rated for up to 3,000 psi working pressure. The valve measures 2.03 inches overall length and 3.55 inches overall height. Both end connections are 3/8 inch male NPT (MNPT), making it suitable for direct inline installation. Plumbers, pipefitters, and HVAC technicians install this type of valve in instrumentation lines, hydraulic circuits, and refrigeration or pneumatic systems where reliable shutoff and throttling are required.

This valve is well suited for commercial and industrial plumbing, HVAC, and pneumatic or hydraulic applications where a compact, high-pressure inline needle valve is needed. The straight body configuration allows straightforward in-line installation between threaded pipe sections. The PTFE seal material provides chemical compatibility with a wide range of media and resists wear under repeated cycling. Both ports accept standard 3/8 inch NPT male fittings, which are common across trade plumbing and mechanical system piping.

Key Features

• Straight body with round handle for manual flow control and shutoff
• Rated to 3,000 psi maximum working pressure
• Brass body construction for corrosion resistance in fluid and gas service
• PTFE seal for broad chemical compatibility and low-friction operation
• 3/8 inch MNPT x MNPT connections for standard threaded pipe installation
• Compact profile at 2.03 inches OAL and 3.55 inches OAH

Compatibility

Designed as an OEM-style replacement or direct-install needle valve for 3/8 inch NPT threaded plumbing, HVAC, pneumatic, or hydraulic system installations requiring high-pressure flow control.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the system completely before removing or installing the valve. Apply thread sealant or tape appropriate for the service media to the MNPT threads before assembly. Verify all connections are leak-free before returning the system to operating pressure.
