Parker 165HD-8 Brass Compression Tube Union 1150 Psi

Product Description

The PARKER 165HD-8 is a brass compression tube union designed to join two compression-end tubing runs in a single, inline connection. It accepts compression fittings on both ends, creating a leak-resistant joint without soldering or threading. Built from brass, this union is suited for use in fluid and gas distribution lines where a reliable, serviceable connection is needed. With a maximum working pressure of 1150 psi, it handles demanding system conditions. Plumbers, HVAC technicians, and refrigeration mechanics commonly install this fitting during new construction, retrofit work, or tubing repair.

This union fits into residential and light commercial applications where compression-style tube connections are standard practice. Typical uses include potable water lines, fuel gas distribution, refrigerant tubing, and pneumatic control lines. Its all-brass construction makes it compatible with copper and compatible soft-metal tubing commonly found in these systems. The compression-by-compression configuration allows the fitting to be installed and removed without specialized crimping or brazing equipment.

Key Features

• Compression x compression end connections for tool-accessible, no-solder installation
• Brass construction provides corrosion resistance and durability in fluid and gas service
• Rated to 1150 psi maximum working pressure for demanding system applications
• Union configuration allows inline tubing connections to be made and serviced in the field
• Compact design suits tight plumbing and mechanical spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for compression tube union applications in plumbing, HVAC, refrigeration, and pneumatic systems using standard compression-end tubing.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians following applicable IPC or IFGC guidelines. Shut off and depressurize the line completely before disassembling or installing any compression fitting. Ensure tubing ends are cut square and deburred before seating the ferrule and nut. Do not overtighten compression nuts, as over-compression can deform the ferrule and cause leaks.
