Parker 164CA-8-8-6 Compression Tube Union Tee Brass

Product Description

The PARKER 164CA-8-8-6 is a three-way compression tube union fitting machined from brass. It connects two 1/2-inch OD tube runs to a 3/8-inch OD branch line using compression-style end connections on all three ports — no soldering or flaring required. Rated to 1000 psi maximum working pressure and a temperature range of -65 to 250 degrees F, this fitting suits demanding fluid and gas plumbing applications in HVAC, refrigeration, and industrial process lines. Plumbers and HVAC technicians install it where a tee junction is needed in copper or compatible soft-metal tubing systems.

This union tee is suited for residential and light commercial installations where a compression-style branch connection is required without the use of heat or specialized tooling. Typical applications include hydronic heating lines, refrigerant distribution where compression fittings are specified, compressed air distribution, and instrumentation tubing. The 1/2 x 1/2 x 3/8-inch port configuration accommodates a common reducing branch scenario in copper tube systems.

Key Features

• Compression end connections on all three ports — no soldering, brazing, or flaring required
• Brass construction for corrosion resistance in water, air, and compatible refrigerant service
• 1000 psi maximum working pressure rating
• Wide service temperature range: -65 to 250 degrees F
• Reducing branch configuration: 1/2 x 1/2 x 3/8-inch tube OD ports
• NPTF thread standard where applicable

Compatibility

Designed for use with 1/2-inch OD and 3/8-inch OD copper or compatible soft-metal tubing in compression-fitting applications. Verify tubing material and system fluid compatibility with brass fittings before installation.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC technicians in accordance with applicable IPC and IFGC codes. Shut off and depressurize the system fully before disconnecting or installing any fitting. Ensure tubing ends are cut square, deburred, and free of contaminants before seating the compression sleeve and nut. Do not overtighten compression nuts — snug by hand then tighten only enough to seat the ferrule and achieve a leak-free connection.
