Parker 8 Pnbz-ss Compression Tube End Cap 1/2 in Ss

Product Description

The PARKER 8 PNBZ-SS is a stainless steel compression tube end cap designed to terminate the open end of a tube in a pressure system. It uses a compression-style end connection, which forms a leak-resistant seal through mechanical compression against the tube outside diameter. Rated to 6300 psi maximum working pressure, this end cap is suitable for demanding hydraulic, pneumatic, and instrumentation applications where system integrity and corrosion resistance are critical. Plumbers, pipefitters, and instrumentation technicians install this fitting when capping off a 1/2-inch OD tube run during system modifications, commissioning, or maintenance.

This end cap fits 1/2-inch outside diameter tubing and is built for use in industrial and commercial tubing systems that require high-pressure termination points. Stainless steel construction makes it well suited for corrosive environments, high-purity fluid systems, and installations where longevity under cyclic pressure is a concern. Typical applications include hydraulic control systems, pneumatic instrumentation lines, chemical processing tubing, and HVAC refrigerant line isolation during service work.

Key Features

• Compression end connection provides a tool-assisted, leak-resistant tube termination without welding or soldering
• Stainless steel construction resists corrosion in wet, chemical, and high-purity service environments
• 6300 psi maximum working pressure rating supports high-pressure hydraulic and instrumentation applications
• Designed for 1/2-inch OD tubing — verify tube OD before installation
• Compact end cap profile minimizes dead-leg volume in terminated lines

Compatibility

Designed as an OEM-style compression fitting for use with 1/2-inch outside diameter tubing in high-pressure fluid and gas systems. No specific system or model compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or instrumentation technician familiar with compression fitting assembly procedures. Depressurize and isolate the tube system fully before removing any existing fittings or installing this end cap. Ensure the tube end is cut cleanly and deburred before seating the ferrule to achieve a proper compression seal. Follow all applicable codes, including ASME B31.3 for process piping or IFGC for gas service, as relevant to the installation.
