Parker 364HB-3N Barbed Tube Union Tee 3/16 Inch Nylon

Product Description

The PARKER 364HB-3N is a single-barb tube union tee fitting designed to join three flexible tubing lines at a common junction point. Molded from white nylon, this fitting accepts tubing with a 3/16 inch inside diameter and a 0.25 inch outside diameter on all three ports. It carries an FDA Compliant and NSF/ANSI 51 certification, making it appropriate for food-equipment and potable-water-adjacent fluid handling applications. The fitting handles pressures up to 125 psi and operates across a temperature range of -40 degrees F to 200 degrees F. At 1.49 inches in overall length and 0.01 pounds, it is a compact, lightweight component suited for tight plumbing assemblies.

This union tee is used in light-duty fluid transfer lines where three tubing runs must connect at a single point without additional hardware. Typical applications include food service equipment, water purification systems, laboratory fluid circuits, and other low-pressure pneumatic or liquid lines where FDA-compliant wetted materials are required. Plumbers, equipment service technicians, and facilities maintenance professionals are the primary installers of this fitting type.

Compatibility

Designed for use with flexible tubing having a 3/16 inch inside diameter and 0.25 inch outside diameter. Suitable as a standard union tee in low-pressure pneumatic and liquid fluid transfer assemblies requiring FDA-compliant or NSF/ANSI 51 certified fittings.

Installation Notes

Push tubing firmly onto each barb until the tubing seats fully behind the barb bead. Verify that all three tubing lines are cut cleanly and squarely before insertion to ensure a leak-free seal. De-pressurize and drain any fluid lines completely before servicing or replacing this fitting. For potable water or food-service applications, confirm that all connected tubing and components also meet the applicable NSF or FDA standards required by local codes.
