Parker 3 Pnbz-ss Compression Tube End Cap Ss

Product Description

The PARKER 3 PNBZ-SS is a stainless steel compression tube end cap designed to terminate and seal the open end of a compression tube line. The fitting uses a standard compression connection, providing a reliable, leak-free seal without welding or brazing. Rated to a maximum working pressure of 10,300 psi, this end cap is built for demanding fluid and instrumentation applications. At 0.034 pounds, it is a compact, lightweight fitting suited for high-pressure tubing systems. Installation is straightforward for licensed plumbers, pipefitters, and instrumentation technicians working in industrial, process, or hydraulic environments.

This end cap is used to blank off or permanently cap a compression tube end in high-pressure fluid handling, instrumentation, or process piping systems. It is appropriate for both residential and commercial applications where stainless steel corrosion resistance and elevated pressure ratings are required. Typical uses include capping unused ports on manifolds, sealing test points, or terminating tubing runs in chemical, oil and gas, or HVAC instrumentation circuits.

Key Features

• Stainless steel construction for corrosion resistance in harsh or wet environments
• Compression end connection eliminates the need for welding or brazing on installation
• Maximum working pressure rating of 10,300 psi suitable for high-pressure instrumentation lines
• Lightweight at 0.034 pounds, minimal added load on tubing assemblies
• Single-piece end cap design provides a clean, permanent tube termination

Compatibility

Designed as an OEM-style compression tube end cap for use with standard compression-style tubing systems in high-pressure fluid and instrumentation applications.

Installation Notes

This fitting should be installed by a qualified pipefitter, plumber, or instrumentation technician. Depressurize and isolate the tubing system completely before removing or installing any compression fittings. Ensure the tube end is cut cleanly and squarely and is free of burrs before seating the compression fitting. Follow applicable codes such as ASME B31.3 for process piping when selecting fittings for high-pressure service.
