Parker 5 Pnbz-ss Compression Tube End Cap Ss 8100 Psi

Product Description

The PARKER 5 PNBZ-SS is a stainless steel compression tube end cap designed to terminate or seal the open end of a compression tube fitting assembly. Rated to a maximum working pressure of 8100 psi, this end cap is built for high-pressure fluid and instrumentation lines where leak-free termination is critical. The compression-style end connection eliminates the need for welding or threading, allowing a secure, repeatable seal directly onto the tube. It is installed by licensed plumbers, pipefitters, and instrumentation technicians working on process, hydraulic, or pneumatic tubing systems.

This end cap suits applications in industrial process lines, instrumentation tubing runs, and high-pressure hydraulic or pneumatic systems where a permanent or serviceable tube termination is required. The stainless steel construction makes it appropriate for corrosive environments, including chemical processing, offshore, and sanitary installations. Its compression fitting end connection supports use anywhere a reliable mechanical tube seal is needed without additional fittings or adapters.

Key Features

• Maximum working pressure rated to 8100 psi for demanding high-pressure service
• Stainless steel construction resists corrosion in harsh and corrosive environments
• Compression-style end connection provides a leak-free, tool-assisted seal without welding or threading
• Compact end cap design seals open tube ends cleanly in finished or temporary installations
• Single-piece package quantity supports low-volume and exact-quantity purchasing

Compatibility

Designed as an OEM-style replacement and standard compression tube end cap for high-pressure stainless steel tubing systems using compression-style fittings.

Installation Notes

Installation is typically performed by a licensed pipefitter, plumber, or instrumentation technician. Before installing or removing any compression fitting, isolate the line and fully depressurize the system. Use the appropriate tube preparation and ferrule seating procedures per the fitting manufacturer guidelines, and ensure the tube end is cut square and deburred before assembly. Follow applicable codes such as ASME B31.3 for process piping when determining pressure ratings and installation requirements.
