Parker 164CA-6-6-4 Brass Compression Tube Union Tee

Product Description

The PARKER 164CA-6-6-4 is a three-way brass compression tube union tee designed to join or branch tubing lines using compression-style end connections on all three ports. It is built for use in fluid and gas distribution systems where a reliable, leak-resistant mechanical connection is required without brazing or soldering. Rated to 1400 psi maximum working pressure and capable of handling temperatures from -65 degrees F to 250 degrees F, this fitting suits demanding service environments. Licensed plumbers, HVAC technicians, and instrumentation technicians typically install this type of fitting in refrigeration, pneumatic, and hydraulic tubing assemblies.

This fitting is suited for residential and commercial applications where tubing lines must be branched or rejoined at a single junction point. Common install scenarios include instrument tubing runs, compressed air distribution, and fluid transfer lines. The all-brass construction makes it appropriate for use with copper or compatible soft metal tubing in both indoor and controlled outdoor environments. All three ports accept standard compression fittings, allowing tool-free disassembly for maintenance or line reconfiguration.

Compatibility

Designed as an OEM-style compression tee fitting for use in pneumatic, hydraulic, refrigeration, and fluid transfer tubing systems that require a three-port union junction with compression-style connections.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or instrumentation technicians following applicable IPC or system-specific codes. Shut off and depressurize the tubing system completely before removing or installing any compression fitting. Ensure tubing ends are cut cleanly and deburred before seating them into the compression ports to achieve a proper seal. Do not overtighten compression nuts, as this can deform the ferrule and compromise the seal.
