Parker 12-12 Hbz-ss Compression Tube Union

Product Description

The PARKER 12-12 HBZ-SS is a stainless steel compression tube union designed to join two compression-end tube lines in a single inline connection. This fitting creates a leak-resistant, mechanically secure joint without welding or brazing, making it well suited for high-pressure fluid and gas systems. Constructed from stainless steel, it withstands demanding environments including exposure to corrosive media, elevated temperatures, and moisture. With a maximum working pressure of 5800 psi, it is appropriate for hydraulic, pneumatic, instrumentation, and process piping applications. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers for this type of fitting.

This compression tube union is used in residential and commercial applications wherever two tube runs must be coupled inline without permanent joining methods. Common install scenarios include instrumentation tubing, hydraulic lines, refrigeration piping, and chemical process systems where stainless steel is required for corrosion resistance. The compression-by-compression end configuration allows for straightforward field assembly and disassembly when servicing or modifying tube runs.

Key Features

• Stainless steel construction for corrosion resistance in harsh or wet environments
• Compression x compression end connections on both sides for tool-assisted, no-weld assembly
• Maximum working pressure of 5800 psi suitable for high-pressure hydraulic and instrumentation service
• Inline union design allows tube runs to be coupled and decoupled without cutting tubing
• Sold individually, no minimum order beyond single-unit purchase

Compatibility

Designed as an OEM-style inline compression union for instrumentation, hydraulic, and process tubing systems requiring stainless steel fittings with compression-style end connections.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or instrumentation technician following applicable IPC or process-system codes. Depressurize and isolate the tube line completely before disassembling or installing any compression fitting. Use the appropriate tube cutter and deburring tool to prepare tube ends squarely before seating the ferrules. Do not overtighten compression nuts beyond the fitting manufacturer's recommended procedure, as this can deform the ferrule and compromise the seal.
