Parker 329HB-12-8N Barbed Tube Male Elbow 3/4 in Barb

Product Description

The PARKER 329HB-12-8N is a single-barb male elbow fitting designed to connect flexible tubing to NPT-threaded ports in fluid-handling systems. It transitions from a 3/4-inch barbed tube end to a 1/2-inch male NPT thread with a 90-degree elbow geometry. The fitting is molded from nylon in white and meets FDA Compliant and NSF/ANSI 51 standards, making it suitable for food-equipment and potable-water adjacent applications. Rated to 125 psi and a maximum working temperature of 200 degrees F, it handles a broad range of low-pressure fluid and air service. Plumbers, HVAC techs, and equipment service technicians install this fitting in systems requiring a direction change from a barbed tube connection to a threaded port.

This fitting is used in residential and light commercial applications where flexible tubing must transition to a fixed NPT-threaded inlet or outlet at a 90-degree angle. Typical installations include ice machine water lines, beverage equipment, cooling system drain lines, and similar low-pressure plumbing circuits. The nylon construction resists corrosion and is compatible with water and many mild fluid media. The single-barb design secures standard flexible tubing with a tube inside diameter of 3/4 inch and a tube outside diameter of 0.81 inches.

Key Features

• Single-barb elbow design transitions 3/4-inch ID flexible tubing to 1/2-inch male NPT thread
• Nylon construction — corrosion-resistant and lightweight
• FDA Compliant and NSF/ANSI 51 certified for food-equipment fluid contact service
• Rated to 125 psi maximum working pressure
• Operating temperature range: -40 degrees F to 200 degrees F (-40 degrees C to 93.3 degrees C)
• White color for easy visual identification in multi-line installations

Compatibility

Designed for use with flexible tubing having a 3/4-inch inside diameter and a 1/2-inch NPT male thread port. Suitable for low-pressure water, air, and mild fluid service in food, beverage, and plumbing equipment where NSF/ANSI 51 compliance is required.

Installation Notes

Installation is performed by plumbers or equipment service technicians. Shut off fluid supply and relieve line pressure before installing or removing any fitting. Apply thread sealant tape or compound to the male NPT threads per IPC guidelines before threading into the female port. Push flexible tubing fully onto the barb until it seats against the fitting shoulder; secure with a hose clamp where required by the application or local code.
