Parker 3 Fnz-ss Compression Tube Plug Stainless Steel

Product Description

The PARKER 3 FNZ-SS is a compression-style tube plug manufactured in stainless steel for use in instrumentation and fluid-handling systems. It terminates an open compression tube end, blocking flow and sealing the line at a rated maximum working pressure of 10300 psi. The stainless steel construction resists corrosion in harsh process environments. This fitting is installed by plumbers, pipefitters, and instrumentation technicians wherever a compression tube run must be capped and pressure-tested or taken out of service.

This plug is suited for high-pressure instrumentation tubing applications in industrial, commercial, and process environments. Its compression-style end connection makes it compatible with standard compression tube fittings, allowing installation without welding or brazing. It is commonly used when decommissioning a branch line, blanking off an unused port, or isolating a section of a fluid system for service.

Key Features

• Compression end connection for tool-assisted, no-weld installation
• Stainless steel construction for corrosion resistance in aggressive media
• Rated to 10300 psi maximum working pressure
• Compact, single-piece plug design terminates tube lines cleanly
• Sold individually — package quantity of one

Compatibility

Designed as an OEM-style compression tube plug for use with standard compression tube fitting systems in high-pressure instrumentation and fluid-handling applications.

Installation Notes

Installation is performed by a qualified pipefitter or instrumentation technician. Depressurize and drain the system completely before removing any fitting or installing this plug. Use the appropriate compression fitting wrench and follow the tube manufacturer's recommended number of turns past finger-tight. Ensure the tubing end is cut square and deburred before seating the compression ferrule.
