Parker 6-6 Hbz-ss Compression Tube Union Ss 6600 Psi

Product Description

The PARKER 6-6 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 reliable performance in demanding fluid and gas distribution systems where corrosion resistance and pressure integrity are required. It is rated for a maximum working pressure of 6600 psi, making it suitable for high-pressure instrumentation, hydraulic tubing, and process piping applications. The compression x compression end connections allow for tool-assisted, leak-resistant assembly without the need for welding or soldering. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.

This fitting is used in residential, commercial, and industrial settings where two tube runs must be connected inline with a reusable, pressure-rated mechanical joint. Common applications include instrumentation tubing, pneumatic control lines, hydraulic circuits, and process fluid systems where stainless steel is specified for compatibility with corrosive media or high-cycle environments. Its compression-style connections make it practical in installations where flame or heat cannot be used.

Key Features

• Stainless steel construction for corrosion resistance in harsh or wet environments
• Rated to 6600 psi maximum working pressure for high-pressure service
• Compression x compression end connections on both sides for inline tube joining
• No welding or soldering required during installation
• Compact union body suits tight plumbing and instrumentation routing

Compatibility

Designed as an OEM-style compression tube union for use in high-pressure tubing systems requiring stainless steel fittings with compression-style end connections on both ports.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or instrumentation technicians following applicable codes such as ASME B31.3 for process piping. Before servicing or installing this fitting, depressurize and isolate the affected tube circuit completely. Compression fittings require proper tube squareness and correct ferrule seating to achieve a leak-free joint — do not overtighten. Always verify system pressure rating compatibility before returning the line to service.
