Parker 165CA-12 Compression Tube Union Brass

Product Description

The PARKER 165CA-12 is a brass compression tube union designed to join two compression-end tube lines in a single inline connection. It provides a leak-resistant, tool-serviceable joint without soldering or threading the tubing itself. Rated to 550 psi maximum working pressure and capable of handling temperatures from -65 degrees F to 250 degrees F, this union suits a wide range of fluid and gas distribution applications. Licensed plumbers, pipefitters, and HVAC technicians install this fitting in both new construction and service work where a removable, reusable tube connection is required.

This fitting is suited for residential and light commercial plumbing, HVAC refrigerant lines, pneumatic systems, and instrumentation tubing runs where compression-style end connections are specified. The union configuration allows technicians to disconnect and reconnect a tube run without cutting or reflaring, making it practical for service access points and equipment connections that require periodic maintenance.

Key Features

• Compression x Compression end connections on both sides for tool-only assembly
• Brass construction provides corrosion resistance in wet and humid environments
• 550 psi maximum working pressure supports a broad range of system designs
• Temperature range of -65 degrees F to 250 degrees F suits heating, cooling, and refrigeration circuits
• NPTF thread standard where applicable ensures pressure-tight engagement
• Union design allows disassembly and reconnection without cutting tubing

Compatibility

Designed as an OEM-style replacement or new-installation fitting for compression tube systems requiring an inline union connection in plumbing, HVAC, pneumatic, or instrumentation applications.

Installation Notes

This fitting is installed by licensed plumbers, pipefitters, or qualified HVAC technicians. Shut off system pressure and depressurize the line fully before disassembly or installation. Ensure tubing ends are cut square and deburred before seating into the compression fitting to achieve a proper seal. Follow applicable IPC and IFGC code requirements for fitting use in pressure systems.
