Parker 6A-V6LN-B Needle Valve 3/8 Inch Compression Brass 3000 Psi

Product Description

The PARKER 6A-V6LN-B is a straight-pattern needle valve designed for precise flow control in high-pressure fluid and gas systems. Built with a brass body and a polytetrafluoroethylene (PTFE) seal, this valve handles pressures up to 3,000 psi. The round handle provides manual control for fine throttling or shutoff. At 2.58 inches overall length and 3.55 inches overall height, it fits into compact installations where space is limited. Licensed plumbers, HVAC technicians, and industrial piping professionals install this valve in instrumentation lines, refrigeration circuits, and process piping where leak-tight shutoff and throttling precision are required.

This valve is suited for residential and light commercial applications involving 3/8 inch compression-end pipe connections. Compression fittings make it a common choice for tubing runs where soldering is not practical or permitted. Typical installation scenarios include instrument root valves, sample lines, and hydraulic or pneumatic test rigs operating within the rated pressure range. The PTFE seal material offers good chemical resistance, making it compatible with a range of media including water, air, and many common refrigerants and process fluids.

Key Features

• Straight-pattern body for in-line installation in 3/8 inch compression tubing runs
• Brass body construction provides corrosion resistance in wet and humid environments
• PTFE seat and seal deliver leak-tight shutoff and chemical compatibility with a broad range of media
• Rated to 3,000 psi maximum working pressure for high-pressure instrumentation and process lines
• Round handle allows precise manual throttling and full shutoff
• Compact overall dimensions of 2.58 inches length and 3.55 inches height suit space-constrained installations

Compatibility

Designed as an OEM-style replacement or new-installation needle valve for 3/8 inch compression-end tubing systems operating at up to 3,000 psi.

Installation Notes

This valve is typically installed by licensed plumbers or HVAC technicians working on pressurized fluid or gas lines. Depressurize and isolate the system completely before removing any existing valve or fitting. Compression fittings should be tightened to manufacturer-recommended hand-tight-plus specifications using appropriate tubing wrenches — do not overtighten. Follow all applicable local plumbing and mechanical codes, including IPC and IFGC guidelines, when installing valves in gas or refrigerant service.
