Parker 364HB-6-4N Barbed Tube Union Tee 3/8 X 1/4 Inch

Product Description

The PARKER 364HB-6-4N is a barbed tube union tee fitting designed to join three fluid or pneumatic lines in a tee configuration using barbed connections. Molded from nylon, it accepts a 3/8-inch barb on one port and 1/4-inch barbs on the remaining ports, allowing transition between two tubing sizes within a single inline junction. The white nylon construction resists corrosion and is suited for low-pressure fluid handling, pneumatic distribution, and similar applications. Plumbers, HVAC technicians, and fluid-system installers use this type of fitting when routing flexible tubing through tight or branched pathways.

This union tee is applicable in residential and light commercial fluid or pneumatic tubing systems. Typical installations include HVAC condensate and drain lines, low-pressure water distribution, pneumatic control tubing, and similar plumbing or fluid-handling assemblies where flexible barbed tubing must be branched or divided. The mixed barb sizing accommodates tubing transitions at the tee junction without additional adapters.

Key Features

• Union tee configuration joins three barbed tubing lines in a single fitting
• 3/8-inch and 1/4-inch barb sizes allow inline tubing size transition
• Nylon construction offers corrosion resistance for fluid and pneumatic service
• White color provides easy visual identification in tubing assemblies
• Lightweight at 0.01 pounds for use in space-constrained installations

Compatibility

Designed as an OEM-style barbed union tee for use with flexible tubing in low-pressure fluid handling and pneumatic plumbing applications where 3/8-inch and 1/4-inch barb connections are required.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or fluid-systems technician. Shut off all fluid or air supply and relieve system pressure before disconnecting or replacing any fitting. Push flexible tubing fully over each barb and secure with appropriate tubing clamps where required by the application or local code. Inspect tubing ends for cracks or deformation before assembly to ensure a leak-free connection.
