Parker 224-6-6-5/32 Barbed Tube Union Tee Brass

Product Description

The PARKER 224-6-6-5/32 is a brass barbed tube union tee designed to join three flexible tubing lines at a single connection point. The tee features multiple barb sizes, accommodating tube outside diameters of 3/8 inch and 5/32 inch on their respective ports, with inside diameter dimensions of 0.25 inch and 0.096 inch. Constructed from brass, this fitting provides solid corrosion resistance in fluid and pneumatic service. It is a push-on barbed design, relying on the tubing's elastic grip over the barbs to maintain a secure, leak-resistant seal without additional fittings or clamps, though clamps may be added for higher-pressure applications.

This union tee is suited for light-duty fluid transfer, pneumatic control lines, and specialty gas distribution in HVAC controls, refrigeration accessory circuits, pool and spa equipment, and similar trade applications. The multi-barb configuration makes it practical for installations that require branching a smaller-diameter pilot or control line off a larger main tubing run. Typical installers include HVAC technicians and plumbers working with flexible tubing in low-pressure systems.

Key Features

• Brass construction for corrosion resistance in fluid and pneumatic service
• Union tee configuration allows three-way branching of flexible tubing lines
• Multiple barb sizes on a single fitting — 3/8 inch OD and 5/32 inch OD ports
• Barbed retention design provides secure grip without threaded connections
• Compact and lightweight at 0.02 pounds — minimal footprint in tight installations

Compatibility

Designed for use with flexible tubing having outside diameters of 3/8 inch and 5/32 inch. Suitable as an OEM-style barbed union tee fitting in low-pressure fluid and pneumatic tubing systems where brass fittings are specified.

Installation Notes

This fitting is installed by licensed HVAC technicians, plumbers, or qualified mechanics working on low-pressure tubing circuits. Shut off and depressurize the system fully before removing or installing any fitting. Push tubing firmly onto each barb past the retention bead for a secure seal; adding tubing clamps is recommended when system pressure or vibration demands it. Do not exceed the pressure rating of the connected tubing or the application system.
