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

Product Description

The PARKER 6Z-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 up to 5,000 psi working pressure while maintaining corrosion resistance in demanding environments. The round handle provides tactile control for fine throttling adjustments. With compression-to-compression end connections sized for 3/8-inch pipe, it delivers a reliable, leak-resistant seal without welding or threading. Licensed plumbers, pipefitters, and HVAC technicians typically install this valve in instrumentation, process piping, and refrigeration service lines.

This needle valve is suited for residential and commercial applications where precise flow isolation or throttling is required. The straight configuration and compression fittings make it a practical choice for instrument tubing runs, hydraulic test points, and refrigerant line service ports. Its stainless steel construction and PTFE seal allow use in corrosive media environments, including water treatment, chemical process lines, and compressed gas systems. Overall assembled length is 2.58 inches and overall assembled height is 3.55 inches, keeping the footprint compact in tight panel or manifold installations.

Key Features

• 316 stainless steel body for corrosion resistance in harsh media and outdoor environments
• PTFE seat and seal for chemical compatibility and low-friction operation
• Maximum working pressure rated at 5,000 psi for high-pressure service
• Compression x compression end connections for 3/8-inch pipe — no threading or welding required
• Round handle for precise manual throttling and flow regulation
• Compact footprint at 2.58 inches overall length and 3.55 inches overall height

Compatibility

Designed as an OEM-style needle valve for 3/8-inch compression fitting systems operating up to 5,000 psi, compatible with instrumentation tubing, process piping, and refrigeration or hydraulic service applications where stainless steel construction and PTFE sealing are specified.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or qualified HVAC technician in accordance with applicable codes including ASME B31.1 or B31.3 for process piping. Depressurize and isolate the line completely before removing any existing valve or fitting. Compression fittings must be assembled to the tubing manufacturer's specifications — do not overtighten, as this can deform the ferrule and compromise the seal. Verify flow direction and pressure rating compatibility with the system before returning the line to service.
