Parker 364HB-4N Barbed Tube Union Tee 1/4 Inch Nylon

Product Description

The PARKER 364HB-4N is a single-barb nylon union tee fitting designed for low-pressure fluid and pneumatic tubing connections. It accepts tubing with a 1/4 inch inside diameter and a 0.32 inch outside diameter on all three ports, creating a branch connection without tools or fasteners. The barbed design grips tubing securely and resists pull-out under normal service conditions. Built from white nylon, this fitting meets FDA compliance and NSF/ANSI 51 food-equipment standards, making it suitable for potable water and food-contact fluid systems. It is rated to 125 psi maximum working pressure across a temperature range of -40 degrees F to 200 degrees F. Plumbers, food service technicians, and OEM equipment assemblers typically install this fitting.

The 364HB-4N is used in residential and light commercial fluid-handling systems where a compact, corrosion-resistant tee connection is required. Typical applications include drinking water equipment, ice makers, refrigeration water lines, beverage dispensing systems, and food processing equipment where NSF/ANSI 51 compliance is required. The overall installed length of 1.92 inches keeps the fitting compact in tight plumbing chases and equipment enclosures. Its all-nylon construction eliminates corrosion concerns common with metal fittings in wet or humid environments.

Installation Notes

Installation is performed by plumbers or equipment technicians following applicable IPC guidelines. Shut off the fluid supply and relieve all line pressure before disconnecting or installing any fitting. Push tubing fully onto each barb until seated against the fitting shoulder to ensure a leak-free grip. For pressure-critical applications, verify the assembled joint with a low-pressure leak test before returning the system to service.
