Parker 3-2 Hbz-ss Compression Tube Union Ss 3/16x1/8

Product Description

The PARKER 3-2 HBZ-SS is a stainless steel compression tube union designed to join two lengths of tubing with mismatched outside diameters in a single inline connection. It accepts a 3/16-inch tube on one end and a 1/8-inch tube on the other, with a maximum working pressure rating of 10300 psi. The all-stainless steel construction provides corrosion resistance in demanding fluid and gas line applications. This fitting is installed by plumbers, HVAC technicians, instrumentation technicians, and industrial piping mechanics working on high-pressure tubing assemblies.

This union is suited for use in hydraulic instrument lines, pneumatic control tubing, refrigeration sensing lines, and other high-pressure fluid transfer systems where a leak-free transition between two different tube sizes is required. Its compression-by-compression end connections make it compatible with standard compression tubing runs in both industrial and commercial installations. No soldering or welding is required, making it practical for field service and tight-space installations.

Key Features

• Stainless steel construction for corrosion resistance in fluid and gas service
• Compression x compression end connections for tool-assisted, no-solder installation
• Reduces between 3/16-inch and 1/8-inch outside diameter tubing in a single union
• Rated to 10300 psi maximum working pressure for high-pressure line applications
• Inline union design maintains straight tubing run without offsets

Compatibility

Designed as an OEM-style compression tube union for high-pressure instrumentation and fluid transfer tubing applications requiring a 3/16-inch to 1/8-inch outside diameter transition.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or instrumentation technician. Depressurize and isolate the tubing circuit completely before disassembling any existing fittings or installing this union. Ensure tubing ends are cut square and deburred before seating into the compression ferrules. Tighten compression nuts to the fitting body per standard compression fitting practice, and verify for leaks before returning the system to service.
