Parker 224-6-6-4 Barbed Tube Union Tee Brass Fitting

Product Description

The PARKER 224-6-6-4 is a barbed tube union tee fitting designed for multi-barb tube connections in fluid and pneumatic systems. Constructed from brass, this union tee joins three tubing lines at a single junction point, allowing flow to split or combine within a system. The fitting accommodates a tube inner diameter of 0.25 x 0.17 inches and a tube outer diameter of 3/8 x 1/4 inches. Its barbed ends grip tubing securely without additional hardware, making it a reliable choice for plumbing, HVAC, and general fluid-handling applications. Licensed tradespeople and experienced technicians install this type of fitting where a compact, leak-resistant branch connection is needed.

This union tee fitting is suited for residential and light commercial fluid or pneumatic tubing runs where a branching connection is required. Typical applications include coolant lines, low-pressure air circuits, water distribution tubing, and similar installations that use flexible tubing in the 1/4 to 3/8 inch OD range. The brass construction makes it compatible with a broad range of compatible tubing materials commonly used in trade applications.

Installation Notes

This fitting is typically installed by plumbers, HVAC technicians, or qualified tradespeople working on low-pressure fluid or pneumatic tubing systems. Shut off fluid or air supply and relieve system pressure before removing or installing any fitting. Ensure tubing is cut cleanly and squarely before seating it onto the barbed ends. Follow applicable IPC or system manufacturer guidelines for maximum pressure and temperature ratings before installation.
