Parker 8-6 Hbz-ss Compression Tube Union Stainless Steel

Product Description

The PARKER 8-6 HBZ-SS is a compression tube union designed to join two compression-end tube lines in a single inline fitting. Constructed from stainless steel, this union provides a leak-resistant, metal-to-metal seal rated for working pressures up to 6300 psi, making it well-suited for high-pressure instrumentation, hydraulic, and fluid-control applications. The compression-by-compression end configuration allows straightforward assembly without welding or brazing. Licensed plumbers, HVAC technicians, and instrumentation fitters working on process piping, refrigeration lines, or fluid conveyance systems will encounter this fitting in both new installations and repair work.

This fitting is appropriate for use in residential, commercial, and light industrial applications where stainless steel corrosion resistance and high-pressure integrity are required. Typical install scenarios include instrument tubing runs, chemical transfer lines, and any system where tube-to-tube connection must maintain a reliable seal under sustained pressure. The compression-by-compression design supports use in tight spaces where flared or welded connections are impractical.

Key Features

• Stainless steel construction provides corrosion resistance in wet, chemical, or outdoor environments
• Maximum working pressure rated to 6300 psi for high-pressure service
• Compression x compression end connections on both sides for tool-assisted, no-weld assembly
• Union configuration allows tube lines to be joined and disconnected without cutting
• Compact, low-profile body suitable for confined installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation compression tube union for systems requiring stainless steel fittings with compression-by-compression end connections at working pressures up to 6300 psi.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified instrumentation technician. Depressurize and isolate the tube line completely before disassembly or installation. Use two wrenches when tightening compression fittings to avoid twisting the tubing. Follow applicable codes such as ASME B31.3 for process piping or the IPC for plumbing systems when selecting and installing compression fittings in pressurized lines.
