Parker 5 Fnz-ss Compression Tube Plug Stainless Steel

Product Description

The PARKER 5 FNZ-SS is a stainless steel compression tube plug designed to terminate or cap off a compression tube line in fluid and gas handling systems. It creates a secure, leak-resistant seal at the end of a compression fitting run without requiring additional tools beyond standard hand-tightening and a wrench. Rated to a maximum working pressure of 8100 psi, this plug suits demanding industrial and instrumentation applications. The stainless steel construction provides corrosion resistance in harsh or wet environments. Plumbers, pipefitters, and instrumentation technicians working on high-pressure tubing systems will find this a reliable solution for dead-ending an open compression port.

This plug is suited for use in high-pressure fluid and gas distribution systems, instrumentation tubing, hydraulic control lines, and process piping applications where a compression-style end cap is required. It is commonly installed during system commissioning, testing, or when temporarily or permanently closing off an unused compression port. Its stainless steel body makes it appropriate for corrosive media environments and outdoor or marine installations.

Key Features

• Maximum working pressure of 8100 psi for demanding high-pressure service
• Stainless steel construction for corrosion resistance in harsh environments
• Compression end connection for tool-minimal, repeatable installation
• Compact plug form factor seals compression tube ends cleanly
• Sold individually, suitable for single-point replacement or repair

Compatibility

Designed as an OEM-style compression tube plug compatible with standard compression fitting systems. Consult Parker fitting specifications to confirm tube size and series compatibility before installation.

Installation Notes

Installation of this compression tube plug should be performed by a licensed pipefitter, plumber, or qualified instrumentation technician. Depressurize and isolate the tubing system completely before removing any fittings or installing this plug. Use two wrenches where applicable to avoid twisting the tubing during tightening. Follow applicable plumbing and piping codes, including ASME and relevant local standards, for high-pressure compression fitting installations.
