Parker 10 Pnbz-ss Compression Tube End Cap 5/8 in Ss

Product Description

The PARKER 10 PNBZ-SS is a compression-style tube end cap manufactured in stainless steel, designed to terminate and seal the open end of a tube in fluid or gas distribution systems. It accepts a tube with a 5/8-inch outside diameter and is rated for a maximum working pressure of 6100 psi, making it suitable for high-pressure instrumentation, hydraulic, and pneumatic tubing lines. The compression fitting design requires no welding or brazing, allowing for a reliable, leak-resistant seal that can be installed and removed with standard hand tools. Plumbers, pipefitters, and instrumentation technicians working with high-pressure tubing systems are the typical installers of this fitting.

This end cap is suited for industrial, commercial, and process-control applications where a tube run must be capped, pressure-tested, or temporarily or permanently closed. Its stainless steel construction provides strong resistance to corrosion, making it appropriate for use in wet environments, chemical processing lines, and outdoor installations where carbon steel fittings would be prone to rust or degradation. The compression connection eliminates the need for soldering, making it a practical choice for field service and maintenance work.

Key Features

• Compression fitting end connection — no welding, brazing, or soldering required
• Stainless steel construction for corrosion resistance in demanding environments
• Rated for up to 6100 psi maximum working pressure
• Fits 5/8-inch outside diameter tubing
• End cap configuration seals and terminates open tube ends cleanly

Compatibility

Designed as an OEM-style compression end cap for 5/8-inch outside diameter tubing in high-pressure fluid and gas distribution systems.

Installation Notes

Installation is performed by licensed pipefitters, plumbers, or instrumentation technicians following applicable codes such as ASME B31.1 or B31.3 for pressure piping systems. De-pressurize and isolate the tubing line fully before removing or installing any compression fitting. Hand-tighten the fitting nut first, then advance with a wrench according to standard compression fitting procedures — do not overtighten, as this can damage the ferrule and compromise the seal. Inspect the ferrule and tube end for damage or burrs before assembly.
