Parker 6-5 Hbz-ss Compression Tube Union Ss 3/8x5/16 6600psi

Product Description

The PARKER 6-5 HBZ-SS is a stainless steel compression tube union designed to join two compression-end tubes in a single in-line fitting. It accepts a 3/8-inch outside diameter tube on one end and a 5/16-inch outside diameter tube on the other, making it suitable for reducing union applications in instrumentation, hydraulic, and pneumatic tubing systems. Rated to a maximum working pressure of 6600 psi, this fitting is built for high-pressure service. It is typically installed by plumbers, pipefitters, or instrumentation technicians working with stainless steel tubing in industrial or process environments.

This union fitting is used in applications requiring a leak-tight, tool-assisted connection between two compression tubes of differing outside diameters. Common installation scenarios include instrument tubing runs, fluid power circuits, and process control lines where stainless steel is specified for corrosion resistance or cleanliness requirements. The compression-by-compression end configuration allows field assembly without welding or brazing.

Key Features

• Stainless steel construction for corrosion resistance in demanding service environments
• Compression x compression end connections for tool-assisted, no-braze field assembly
• Reducing union design accepts 3/8-inch OD tube on one end and 5/16-inch OD tube on the other
• Rated to 6600 psi maximum working pressure for high-pressure instrumentation and fluid systems
• Compact and lightweight at 0.11 pounds for easy handling in tight tubing runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for stainless steel compression tubing systems using 3/8-inch and 5/16-inch outside diameter tube.

Installation Notes

Installation is performed by a licensed plumber, pipefitter, or instrumentation technician. Depressurize and isolate the tubing circuit completely before disassembling any compression fittings. Ensure tube ends are cut square and deburred before seating into the compression ferrule to achieve a proper seal. Follow applicable plumbing and instrumentation codes for high-pressure tubing assembly and inspection.
