Parker MP11870 Barbed Tube Union Tee 0.17 Inch Id

Product Description

The PARKER MP11870 is a brass barbed tube union tee designed to split or join flexible tubing in fluid handling and pneumatic systems. The union tee configuration allows three lines to connect at a single junction without threaded fittings or tools, relying on barbed retention to hold tubing securely. It is sized for tubing with a 0.17-inch inside diameter and a 1/4-inch outside diameter. Brass construction provides corrosion resistance and durability in both liquid and low-pressure air applications. HVAC technicians, plumbers, and equipment service techs typically install these fittings when routing coolant lines, drain lines, or instrument tubing.

This fitting is suited for residential and light commercial applications where flexible tubing must be branched or joined at a tee junction. Common install scenarios include condensate drain networks, equipment coolant loops, and pneumatic control line assemblies. The compact barbed design works with standard flexible tubing in the corresponding ID and OD range. It ships in a package quantity of five units, making it practical for service vans and bench stock.

Key Features

• Barbed ends provide pull-resistant retention without clamps on low-pressure lines
• Brass material resists corrosion in wet and fluid-handling environments
• Sized for 0.17-inch inside diameter and 1/4-inch outside diameter tubing
• No threading or special tooling required for installation
• Packaged in quantities of five for efficient restocking

Compatibility

Designed as an OEM-style replacement or service fitting for flexible tubing systems requiring a union tee junction at 0.17-inch ID and 1/4-inch OD tubing specifications.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or equipment service professionals during system assembly or repair. Shut off fluid flow and depressurize the line before removing or installing any fitting. Ensure tubing is cut cleanly and squarely and pushed fully onto each barb to achieve a proper seal. Follow applicable codes such as the IPC or IFGC when integrating into code-governed piping systems.
