Parker 2 Fnz-ss Compression Tube Plug 1/8 in Od

Product Description

The PARKER 2 FNZ-SS is a compression-style tube plug designed to seal the open end of a tubing line. It threads onto or inserts into a compression fitting seat to close off flow in instrumentation, fluid, or pneumatic systems. Machined from stainless steel, it resists corrosion in demanding service environments. The 1/8 inch outside diameter connection handles maximum working pressures up to 10900 psi, making it appropriate for high-pressure instrumentation and hydraulic tubing applications. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers. Its compact form and single-piece construction make it straightforward to deploy in tight panel or manifold locations.

This plug is suited for residential and commercial instrumentation lines, high-pressure fluid systems, and pneumatic tubing assemblies where a compression-terminated end cap is required. It is used when a tube run must be capped off cleanly without welding or brazing. The stainless steel material makes it appropriate for corrosive media, outdoor installations, and sanitary or chemical process applications where carbon steel fittings would be unsuitable.

Key Features

• Compression fitting type for tool-free, leak-tight tube termination
• Stainless steel construction for corrosion resistance in aggressive environments
• 1/8 inch tube outside diameter connection
• Rated to 10900 psi maximum working pressure
• Single-piece design with no separate ferrule or nut required for the plug body

Compatibility

Designed as an OEM-style compression tube plug compatible with 1/8 inch outside diameter tubing in standard compression fitting systems.

Installation Notes

Installation is performed by qualified pipefitters or instrumentation technicians following applicable system codes. Depressurize and isolate the tubing circuit completely before removing or installing any compression fitting. Finger-tighten the compression connection first, then use a wrench to achieve a proper bite on the tubing without over-tightening, which can deform the ferrule and compromise the seal. Verify system pressure rating compatibility before returning the line to service.
