Parker 8 Fnz-ss Compression Tube Plug Stainless Steel

Product Description

The PARKER 8 FNZ-SS is a stainless steel compression tube plug designed to seal the open end of a compression fitting or tubing line. Rated to a maximum working pressure of 6300 psi, this plug provides a reliable, leak-free termination in high-pressure fluid and instrumentation systems. The compression-style end connection creates a mechanical seal directly on the tube outer diameter without the need for solder, flare tools, or thread sealant. It is installed by licensed plumbers, pipefitters, and instrumentation technicians working on process, hydraulic, and pneumatic tubing systems.

This compression tube plug is suited for residential and commercial applications where a tubing run must be capped or temporarily terminated. Common install scenarios include instrument tubing manifolds, hydraulic test lines, and compressed air distribution systems. The stainless steel construction makes it appropriate for corrosive environments and lines carrying aggressive media where brass or copper fittings are not acceptable.

Key Features

• Stainless steel body resists corrosion in demanding fluid and gas service environments
• Compression end connection seals directly on tube OD without solder or thread sealant
• Maximum working pressure of 6300 psi supports high-pressure instrumentation and hydraulic applications
• Compact plug form factor caps open tubing ends cleanly and securely
• Single-piece design simplifies inventory and installation

Compatibility

Designed as an OEM-style compression tube plug compatible with standard compression-style tubing fittings in instrumentation, hydraulic, and pneumatic systems where the tube outer diameter matches the fitting series.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or instrumentation technician. Depressurize and isolate the tubing line completely before installing or removing any compression fitting. Use appropriate tubing cutters and deburring tools to ensure a clean, square tube end before seating the compression ferrule. Follow applicable system design codes and manufacturer torque guidance for the fitting series in use.
