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

Product Description

The PARKER 8-8 HBZ-SS is a stainless steel compression tube union designed to join two compression-end tube lines in a single inline fitting. It creates a secure, leak-resistant connection without the need for brazing or soldering. Rated to 6300 psi maximum working pressure, this union is built for high-demand fluid and gas transfer applications where joint integrity is critical. The all-stainless steel construction resists corrosion in harsh service environments. Plumbers, HVAC technicians, and instrumentation contractors install this fitting in both new construction and retrofit work.

This compression tube union suits residential and commercial applications where two compression-end tube runs must be coupled inline. Typical installations include refrigeration and instrumentation tubing systems, hydraulic lines, and process fluid circuits that require a reliable, pressure-rated union without welded connections. Its compression-by-compression end configuration allows quick field assembly using standard compression fittings tools.

Key Features

• Maximum working pressure of 6300 psi for high-pressure service
• Stainless steel construction for corrosion resistance in demanding environments
• Compression x compression end connections — no brazing or soldering required
• Union configuration allows inline tube joining and future disassembly
• Compact design suitable for tight installation spaces

Compatibility

Designed as an OEM-style replacement or direct-install compression tube union for systems requiring compression x compression inline connections rated to high working pressures.

Installation Notes

Installation is performed by a licensed plumber, HVAC technician, or instrumentation mechanic. Depressurize and isolate the line fully before disassembling or installing any compression fitting. Ensure tubing ends are cut cleanly and deburred to achieve a proper compression seal. Follow applicable plumbing and mechanical codes for the jurisdiction, including IPC and ASME B31 guidelines where required.
