Parker 4 Pnbz-ss Compression Tube End Cap Ss

Product Description

The PARKER 4 PNBZ-SS is a stainless steel compression tube end cap designed to terminate and seal the open end of a compression-style tubing run. It accepts tubing via a standard compression connection, creating a pressure-tight closure without welding or threading. Rated to 10,300 psi maximum working pressure, this fitting is built for demanding fluid and gas distribution systems where leak integrity is critical. Licensed plumbers, industrial pipefitters, and instrumentation technicians are the primary installers. Its stainless steel construction resists corrosion in aggressive media and wet environments.

This end cap is suited for use in hydraulic, pneumatic, instrumentation, and process piping applications where a secure, reusable termination is required. Typical install scenarios include capping unused branch lines, blanking off test ports, or sealing tube ends during system commissioning or maintenance. The compression fitting design allows the cap to be installed and removed without specialized tooling, making it practical for field service and panel work.

Key Features

• Maximum working pressure rated to 10,300 psi for high-pressure system use
• Stainless steel construction for corrosion resistance in harsh or wet environments
• Compression end connection — no welding, soldering, or threading required
• Reusable design supports maintenance, commissioning, and line modifications
• Compact single-piece end cap form factor minimizes dead-leg volume

Compatibility

Designed as an OEM-style compression tube end cap for use in high-pressure instrumentation, hydraulic, and process tubing systems compatible with Parker compression fitting standards.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or instrumentation technicians familiar with compression fitting assembly. Depressurize and isolate the tubing line completely before installing or removing the end cap. Ensure tubing end is cut square, deburred, and clean before seating the compression ferrule. Follow applicable system codes and the fitting manufacturer's assembly instructions for proper ferrule engagement.
