Parker 165CA-8 Brass Compression Tube Union 750 Psi

Product Description

The PARKER 165CA-8 is a brass compression tube union designed to join two compression-end tube lines in a single straight connection. It handles working pressures up to 750 psi and operates across a wide temperature range of -65 degrees F to 250 degrees F, making it suitable for demanding fluid and gas transfer applications. The all-brass construction provides corrosion resistance and reliable sealing in both wet and dry service environments. Licensed plumbers, HVAC technicians, and industrial piping contractors install this fitting where a leak-free, tool-assisted tube-to-tube union is required without the need for soldering or brazing.

This union is suited for residential and light commercial plumbing, HVAC refrigerant-adjacent tubing, and instrumentation lines where compression fittings are the specified connection method. The compression x compression end configuration allows it to connect two tube runs of compatible outside diameter inline. Its rated temperature and pressure performance makes it appropriate for hydronic systems, compressed air lines, and similar mechanical piping applications where brass fittings meet code and material requirements.

Key Features

• Brass construction for corrosion resistance and long service life in wet or humid environments
• Maximum working pressure of 750 psi for demanding pneumatic and fluid system use
• Wide temperature rating from -65 degrees F to 250 degrees F
• Compression x compression end connections on both sides for tool-assisted, no-solder installation
• Union body style allows tube disconnection and reconnection without cutting the line
• NPTF thread standard for pressure-tight engagement where applicable

Compatibility

Designed as an OEM-style replacement or new-installation compression union for brass-compatible tubing systems in plumbing, HVAC, and instrumentation piping where compression fittings are specified.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC technicians. Shut off and depressurize the line completely before disassembling any compression fitting. Ensure tube ends are cut square and deburred before seating them into the compression nut and ferrule. Do not overtighten compression nuts; follow the fitting manufacturer's standard hand-tight-plus-turns procedure appropriate for brass compression fittings.
