Parker 329HB-10-8N Barbed Tube Male Elbow 5/8 in Nylon

Product Description

The PARKER 329HB-10-8N is a single-barb male elbow fitting designed to connect flexible tubing to a threaded male NPT port in a 90-degree configuration. Built from white nylon, this fitting accepts a 5/8 inch tube inside diameter and threads into a 1/2 inch NPT female port. It is rated for working pressures up to 125 psi and handles temperatures from -40 degrees F to 200 degrees F. The nylon construction meets FDA compliance and NSF/ANSI 51 standards, making it suitable for food-equipment and potable-water adjacent plumbing applications. Plumbers, refrigeration technicians, and equipment service pros install this type of fitting in low-pressure fluid and tubing systems.

This fitting is used in residential and light commercial applications where flexible tubing must transition to a threaded NPT connection at a right angle. Typical install scenarios include ice machine supply lines, beverage dispensing equipment, food service plumbing, and similar low-pressure fluid-handling systems where NSF/ANSI 51 compliance is required. The elbow orientation reduces stress on tubing runs that cannot accommodate a straight fitting.

Key Features

• Single barb design secures flexible tubing without additional clamps in low-pressure service
• 5/8 inch barb fits tubing with 5/8 inch inside diameter and approximately 0.68 inch outside diameter
• 1/2 inch NPT male thread for direct connection to standard female NPT ports
• Rated to 125 psi working pressure
• Operating temperature range of -40 degrees F to 200 degrees F (-40 degrees C to 93.3 degrees C)
• FDA Compliant and NSF/ANSI 51 certified for food-zone and potable-water adjacent use

Compatibility

Designed for use with flexible tubing having a 5/8 inch inside diameter and a 1/2 inch NPT female threaded port. Suitable for systems requiring NSF/ANSI 51 compliant fittings in food equipment and related low-pressure fluid-handling applications.

Installation Notes

This fitting is typically installed by plumbers or equipment service technicians. Shut off the water or fluid supply and relieve system pressure before installation. Hand-tighten the NPT thread first, then use a wrench for final tightening — do not overtighten nylon fittings, as the material can crack under excessive torque. Confirm tubing is fully seated past the barb and that the system operating pressure does not exceed the 125 psi rating.
