Parker 164VL-4 Brass Compression Tee Union 600 Psi

Product Description

The PARKER 164VL-4 is a brass compression tee union fitting designed for fluid and gas line connections in industrial and trade plumbing applications. It features three compression-style end connections using Parker's Vibra-Lok compression design, which provides a secure, vibration-resistant seal without soldering or special tools. Rated to 600 psi maximum working pressure and suitable for operating temperatures from -30 degrees F to 275 degrees F, this fitting is built for demanding service conditions. It is sized for use in tubing systems where a three-way union connection is required.

This tee union fitting is commonly installed in hydraulic lines, pneumatic circuits, refrigeration tubing runs, and general-purpose fluid distribution systems. Its all-brass construction suits potable water, fuel, oil, and compressed air service. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting in both residential and light commercial applications where a reliable compression connection at a tee junction is needed. The Vibra-Lok compression style is particularly suited for installations subject to vibration or thermal cycling.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified HVAC technicians. Shut off and depressurize the line completely before disassembling or installing any compression fitting. Ensure tubing ends are cut cleanly and deburred before seating into the compression fitting to achieve a proper seal. Follow applicable IPC, IFGC, or NEC guidelines as relevant to the service type and jurisdiction.
