Parker 6A-V6LN-SS Needle Valve 3/8 in Compression Ss 5000 Psi

Product Description

The PARKER 6A-V6LN-SS is a straight-pattern needle valve designed for precise flow control in high-pressure fluid and gas systems. Built with a 316 stainless steel body and a polytetrafluoroethylene (PTFE) seal, this valve handles working pressures up to 5,000 psi while resisting corrosion and chemical attack. The round handle allows for controlled throttling in tight spaces. At 2.58 inches overall length and 3.55 inches overall height, it fits compactly into instrumentation and process lines. Licensed plumbers, HVAC technicians, and industrial pipefitters install this type of valve in systems where repeatable shutoff and fine flow adjustment are required.

This needle valve is suited for use in instrumentation tubing, hydraulic lines, refrigeration circuits, and chemical process piping where a 3/8-inch compression end connection is specified. The compression fitting end allows for secure, leak-resistant connections to tubing without welding or threading. The straight body style simplifies in-line installation in both residential and commercial applications where precise flow isolation or metering is needed.

Key Features

• 316 stainless steel body for corrosion resistance in aggressive media
• PTFE seal material provides chemical compatibility across a broad range of fluids and gases
• Rated to 5,000 psi maximum working pressure
• Compression end fitting for tool-assisted, leak-resistant tube connections
• Round handle design for controlled, repeatable valve adjustment
• Compact form factor: 2.58 inches overall length, 3.55 inches overall height

Compatibility

Designed as an OEM-style inline needle valve for 3/8-inch compression tube fittings in high-pressure instrumentation, hydraulic, and process piping applications.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified instrumentation technician following applicable codes such as the IPC or relevant ASME standards. Depressurize and isolate the line completely before removing or installing any valve. Use appropriate tubing cutters and deburring tools to prepare compression ends for a proper seat. Do not exceed the rated working pressure of 5,000 psi for this assembly.
