Parker 364HB-5N Barbed Tube Union Tee 5/16 Inch Nylon

Product Description

The PARKER 364HB-5N is a single-barb nylon union tee fitting designed for low-pressure fluid transfer applications. It connects three sections of flexible tubing at a 5/16-inch barb size, accommodating tube inside diameters of 5/16 x 5/16 inches and tube outside diameters of 0.36 x 0.36 inches. Constructed from white nylon, this fitting carries FDA compliance and meets NSF/ANSI 51 standards, making it suitable for food-equipment and potable-water-adjacent fluid lines. The overall length is 2.22 inches and the fitting weighs 0.01 pounds. Licensed plumbers, HVAC technicians, and equipment service techs install this type of fitting in tubing assemblies where a tee branch connection is required.

This fitting is suited for residential and light commercial fluid-handling systems where flexible tubing runs require a branched connection point. Common applications include ice maker supply lines, condensate drain assemblies, food-service equipment fluid circuits, and water treatment plumbing. The NSF/ANSI 51 rating makes it appropriate for food-zone equipment environments. It operates across a working temperature range of -40 degrees F to 200 degrees F and withstands a maximum working pressure of 125 psi, covering most low-pressure hydronic and fluid transfer service scenarios.

Key Features

• 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)

Compatibility

Designed as an OEM-style barbed union tee for flexible tubing with a 5/16-inch inside diameter and 0.36-inch outside diameter in low-pressure fluid transfer systems requiring FDA and NSF/ANSI 51 compliance.

Installation Notes

Installation is typically performed by a licensed plumber or qualified HVAC or equipment service technician. Shut off fluid supply and relieve system pressure before disconnecting existing tubing or installing this fitting. Push tubing firmly onto each barb until it seats fully past the barb bead; a tubing clamp is recommended to secure each leg and prevent pull-off under pressure. Verify that the tubing material and system pressure do not exceed the fitting ratings before returning the system to service.
