Eaton 1064X4 Barbed Tube Union Tee 0.25 in Brass

Product Description

The EATON 1064X4 is a barbed tube union tee fitting designed to join three lengths of flexible tubing at a single junction point. Constructed from brass, this fitting accepts tubing with a 0.25 inch outside diameter on all three ports. The barbed ends grip the inner wall of the tubing to maintain a secure, leak-resistant connection without additional clamps in low-pressure applications. It is a compact, lightweight component at 0.02 pounds and is commonly installed by HVAC technicians, plumbers, and refrigeration service professionals working with small-diameter tubing runs in equipment or control systems.

This union tee is suited for use in residential and light commercial applications where a three-way split or junction is needed in a flexible tubing line. Typical install scenarios include condensate drain lines, refrigeration equipment tubing, and similar small-bore fluid or gas transfer systems. The union-style design allows the fitting to be inserted mid-run without requiring access to the tubing ends, which simplifies service and repair work on existing lines.

Key Features

• Barbed union tee configuration connects three tubing runs at one fitting
• Brass construction provides corrosion resistance and durability in fluid-handling applications
• 0.25 inch tube OD barb size fits standard small-diameter flexible tubing
• Union-style design allows mid-line installation without cutting the full run free
• Lightweight at 0.02 pounds — minimal load on tubing assemblies

Compatibility

Designed as an OEM-style replacement barbed union tee fitting for flexible tubing with a 0.25 inch outside diameter, as used in residential and light commercial HVAC, plumbing, and refrigeration equipment.

Installation Notes

Installation is typically performed by a licensed HVAC technician or plumber. Before servicing any tubing line, shut off fluid or gas flow and relieve pressure in the line. Push tubing firmly over each barbed port until it seats fully past the barb to ensure a secure grip. For pressurized systems, verify that the operating pressure does not exceed the rated limits of both the fitting and the tubing material before returning the system to service.
