Parker 164CA-2 Brass Compression Tee Union 5/16-24

Product Description

The PARKER 164CA-2 is a brass compression tee union fitting designed for three-way tube connections in fluid and gas line assemblies. It features compression-style end connections on all three ports, allowing secure, tool-assisted tube attachment without soldering or flaring. Rated to 2800 psi maximum working pressure and capable of handling temperatures from -65 degrees F to 250 degrees F, this fitting suits demanding environments where leak-free performance is critical. The compact overall length of 0.84 inches makes it suitable for installations with limited space. Plumbers, HVAC technicians, and instrumentation mechanics routinely specify compression fittings of this type for copper and compatible tubing runs.

The 164CA-2 is used in residential and light commercial plumbing, refrigeration, pneumatic control lines, and hydraulic instrument tubing. Its tee configuration allows a single inline run to branch to a third port, which is common in manifold-style installations, bypass loops, and sampling lines. The 5/16-24 thread size and NPTF thread standard make it compatible with standard compression tube fittings in that size range. Brass construction provides corrosion resistance suitable for water, air, and many hydraulic fluids.

Compatibility

Designed as an OEM-style replacement or direct-install compression tee union for tube lines using 5/16-24 NPTF compression fittings in plumbing, HVAC, and fluid instrumentation applications.

Installation Notes

Installation of compression fittings is typically performed by licensed plumbers or HVAC technicians. Depressurize and drain the line fully before disassembly or fitting installation. Compression fittings require correct tube preparation — ensure tube ends are cut square and free of burrs before seating the ferrule. Do not overtighten; follow the fitting manufacturer's recommended turn-past-finger-tight practice to avoid ferrule damage and fitting failure.
