Parker 364HB-8-6N Barbed Tube Union Tee 1/2 X 3/8 Inch Nylon

Product Description

The PARKER 364HB-8-6N is a single-barb union tee fitting designed for joining three lengths of flexible tubing at a common junction point. Molded from white nylon, this tee accepts tube inside diameters of 1/2 inch on one end and 3/8 inch on the remaining ports, with corresponding tube outside diameters of 0.55 inches and 0.43 inches. It is rated to a maximum working pressure of 125 psi and handles temperatures from -40 degrees F to 200 degrees F. The overall length is 2.52 inches. Plumbers, HVAC technicians, and food-equipment service professionals install this fitting where a tubing branch connection is needed in low-pressure fluid or pneumatic lines.

This fitting is suited for residential and light commercial applications involving flexible tubing runs in potable water, beverage dispensing, food processing equipment, and HVAC condensate or drain lines. Its FDA-compliant, NSF/ANSI 51 certification makes it appropriate for food-zone and potable-water contact environments where material compliance is a code or contract requirement. The single-barb design relies on the tubing wall gripping the barb for retention; clamps or ties are commonly added in higher-vibration or pressure-cycled installations.

Key Features

• Single-barb union tee configuration joins three tubing legs without tools
• Nylon construction resists corrosion and is compatible with a broad range of water-based fluids
• FDA compliant and NSF/ANSI 51 certified for food-equipment and potable-water contact applications
• Rated to 125 psi maximum working pressure
• Wide temperature range: -40 degrees F to 200 degrees F (-40 degrees C to 93.3 degrees C)
• Compact overall length of 2.52 inches keeps installation footprint small in tight spaces

Compatibility

Designed for use with flexible tubing having a 1/2 inch inside diameter on the primary port and 3/8 inch inside diameter on the branch ports, corresponding to outside diameters of approximately 0.55 inches and 0.43 inches respectively. Typical fitment in low-pressure fluid and pneumatic tubing systems where barbed union tee fittings are specified.

Installation Notes

Installation does not require special tools; push the tubing firmly over each barb until it seats fully against the fitting body. Shut off and depressurize the fluid or pneumatic line before making or breaking any connection. For installations near the maximum rated pressure or in vibration-prone environments, secure tubing with appropriate clamps per system design requirements. Verify that the fluid medium and any cleaning or sanitizing agents are chemically compatible with nylon before placing the fitting in service.
