Parker 12-6 Hbz-ss Compression Tube Union Ss 3/4x3/8 5800psi

Product Description

The PARKER 12-6 HBZ-SS is a stainless steel compression tube union designed to join two compression-end tube lines in a single inline fitting. It connects a 3/4-inch outside diameter tube on one end to a 3/8-inch outside diameter tube on the other, making it a reducing union suitable for systems that require a transition between two different tube sizes. Rated to 5800 psi maximum working pressure, this fitting is built for high-pressure fluid and gas service. The all-stainless steel construction resists corrosion in demanding environments. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers.

This compression tube union suits a wide range of applications including hydraulic lines, pneumatic systems, refrigeration tubing, instrumentation, and process fluid systems where a leak-free mechanical connection between two different tube sizes is required. The compression-by-compression end configuration eliminates the need for welding or soldering at the joint. It is appropriate for both industrial and commercial installations where stainless steel material compatibility and elevated working pressure are required criteria.

Key Features

• Reducing compression union connects 3/4-inch OD tube to 3/8-inch OD tube without welding or brazing
• 5800 psi maximum working pressure rating for high-pressure service
• Stainless steel construction provides corrosion resistance in wet, chemical, or outdoor environments
• Compression x compression end connections on both sides for tool-assisted, repeatable sealing
• Compact inline form factor for tight plumbing runs and panel installations

Compatibility

Designed as an OEM-style compression fitting replacement for systems requiring a 3/4-inch by 3/8-inch outside diameter tube union with compression end connections and stainless steel material compatibility.

Installation Notes

This fitting is typically installed by licensed plumbers, pipefitters, or instrumentation technicians. Shut off and depressurize the system completely before disassembling existing lines or installing this union. Use the appropriate tube cutter to ensure a clean, square tube end before seating the compression ferrule, and tighten to the fitting manufacturer's standard finger-tight-plus-turns procedure without over-torquing. Verify system pressure rating compatibility before returning the line to service.
