Parker 165CA-5 Compression Tube Union Brass 1200 Psi

Product Description

The PARKER 165CA-5 is a brass compression tube union designed to join two compression-end tube runs in a single inline fitting. It provides a leak-resistant mechanical connection without soldering or brazing, making it a practical choice for refrigeration, HVAC, and plumbing applications where field assembly speed matters. Rated to 1200 psi maximum working pressure and a temperature range of -65 degrees F to 250 degrees F, this union handles demanding pressure and thermal conditions. Licensed HVAC technicians, plumbers, and pipefitters are the typical installers for this type of fitting.

The 165CA-5 suits residential and light commercial systems where compression-style tube connections are specified. Common install scenarios include refrigerant line repairs, instrumentation tubing runs, and hydraulic or pneumatic control lines that fall within the fitting's rated pressure and temperature envelope. The compression x compression end configuration allows connection of two tube ends without requiring threaded pipe ends on either side of the joint.

Key Features

• Brass construction provides corrosion resistance and good machinability for reliable compression seat formation
• Compression x compression end connections on both sides eliminate the need for soldering or brazing at the joint
• 1200 psi maximum working pressure supports high-demand refrigeration and hydraulic applications
• Wide temperature range of -65 degrees F to 250 degrees F suits both low-temperature refrigerant and elevated-temperature fluid service
• NPTF thread standard where applicable ensures pressure-tight engagement
• Inline union configuration allows straight tube-to-tube coupling in a compact body

Compatibility

Designed as an OEM-style replacement or new-installation compression tube union for systems requiring compression x compression brass fittings rated to 1200 psi within the specified temperature range.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or pipefitter. Depressurize and isolate the system completely before removing any existing fitting or cutting into a tube run. Ensure the tube end is cut squarely, deburred, and free of scoring before seating the compression ferrule, as surface defects are a common source of leaks at compression joints. Verify that the tubing material and outer diameter are compatible with the fitting before final assembly.
