Parker 6 Fnz-ss Compression Tube Plug Stainless Steel

Product Description

The PARKER 6 FNZ-SS is a stainless steel compression tube plug designed to seal the open end of a compression fitting connection. It accepts a compression-style tube end and provides a leak-tight closure rated to 6600 psi maximum working pressure. The stainless steel construction resists corrosion in aggressive media and harsh service environments. Plumbers, pipefitters, and instrumentation technicians install this fitting type when capping unused ports or temporarily or permanently sealing tubing runs during system maintenance, testing, or staged installation work.

This compression tube plug is suited for use in industrial fluid systems, instrumentation lines, hydraulic test rigs, and process piping where a reliable, high-pressure seal is required at an open tube terminus. Its all-stainless construction makes it appropriate for applications involving moisture, chemicals, or sanitary requirements. It is packaged and sold as a single fitting, making it practical for targeted repairs or small-quantity installations.

Key Features

• 6600 psi maximum working pressure rating for demanding high-pressure service
• Stainless steel construction provides corrosion resistance in wet, chemical, and sanitary environments
• Compression end connection for tool-assisted, leak-tight tube sealing without welding or soldering
• Compact plug geometry minimizes installation space requirements
• Single-unit packaging supports maintenance and repair applications

Compatibility

Designed as an OEM-style replacement and general-service compression tube plug compatible with standard compression-style tubing systems requiring a high-pressure-rated stainless steel end cap.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or instrumentation technicians following applicable pressure system codes. Depressurize and isolate the tubing circuit completely before removing any existing fittings or installing this plug. Use appropriate tube preparation tools to ensure the tube end is cut square, deburred, and clean before seating the compression ferrule. Do not exceed the rated working pressure of the fitting or the tubing assembly.
