Parker 329HB-6-4N Barbed Male Elbow 3/8 in Barb 1/4 Npt

Product Description

The PARKER 329HB-6-4N is a single-barb male elbow fitting designed to connect flexible tubing to a threaded port in a 90-degree configuration. Made from white nylon, it accepts 3/8-inch inside-diameter tubing and threads into a 1/4-inch NPT male port. The fitting is rated for working pressures up to 125 psi and handles temperatures from -40 degrees F to 200 degrees F. It meets FDA compliance and NSF/ANSI 51 standards, making it appropriate for food-equipment and potable-water applications. Plumbers, HVAC technicians, and food-service equipment installers use this style of fitting where a quick, secure tubing connection to a threaded port is required.

This fitting is suited for residential and light commercial plumbing, food-processing equipment, beverage dispensing systems, and HVAC condensate or fluid-transfer lines where nylon construction and NSF/ANSI 51 certification are required. The male NPT thread allows direct installation into female-threaded ports on valves, manifolds, pumps, or equipment housings. It is appropriate for use with compatible flexible nylon or polyethylene tubing with a 3/8-inch inside diameter and approximately 0.43-inch outside diameter.

Key Features

• Single-barb design secures 3/8-inch ID flexible tubing without additional fittings
• 1/4-inch NPT male thread for direct connection to standard female-threaded ports
• Nylon construction resists corrosion and is compatible with water and many fluid media
• FDA compliant and NSF/ANSI 51 certified for food-equipment and potable-water use
• Rated to 125 psi working pressure across a -40 degrees F to 200 degrees F temperature range
• 90-degree elbow configuration reduces tubing stress in tight or angled routing situations

Compatibility

Designed for use with flexible tubing having a 3/8-inch inside diameter and approximately 0.43-inch outside diameter. Threads into any standard 1/4-inch NPT female port.

Installation Notes

Installation is typically performed by licensed plumbers or qualified HVAC or equipment technicians. Shut off fluid supply and relieve system pressure before removing or installing any fitting. Apply thread sealant or PTFE tape to the NPT threads in accordance with the applicable plumbing code before tightening. Push tubing fully onto the barb until it seats past the barb ridge to ensure a leak-free connection; do not over-torque the NPT thread into plastic-bodied ports.
