Parker 329HB-6-8PP Barbed Male Elbow 3/8 in Barb 1/2 in Npt

Product Description

The PARKER 329HB-6-8PP is a single-barb male elbow fitting designed to connect flexible tubing to a threaded male NPT port at a 90-degree angle. Manufactured from polypropylene in a black finish, this fitting accepts tubing with a 3/8 inch inside diameter and mates to a 1/2 inch NPT threaded port. It is rated for working pressures up to 125 psi and a temperature range of 0 degrees F to 212 degrees F. Compliance with FDA and NSF/ANSI 51 standards makes it appropriate for food-equipment and beverage-dispensing fluid circuits. Plumbers, HVAC technicians, and equipment service technicians install this type of fitting where a low-profile directional change is needed in a tubing run.

This fitting is suited for light commercial and residential fluid-handling applications including food-service equipment, water filtration systems, beverage dispensing, and HVAC condensate lines. The single-barb design grips flexible tubing securely when used with an appropriate clamp. The male NPT thread allows direct connection to female-threaded ports on pumps, valves, tanks, and manifolds. Applications typically involve water, mild aqueous solutions, and other fluids compatible with polypropylene within the listed temperature and pressure limits.

Key Features

• Single-barb design retains flexible tubing on 3/8 inch ID tube connections
• 1/2 inch NPT male thread for direct connection to standard female-threaded ports
• Polypropylene construction resists corrosion and is compatible with many aqueous fluids
• Rated to 125 psi maximum working pressure
• Operating temperature range of 0 degrees F to 212 degrees F
• FDA compliant and NSF/ANSI 51 certified for food-equipment fluid contact

Compatibility

Designed as an OEM-style replacement or new-installation fitting for flexible tubing with a 3/8 inch inside diameter and 0.43 inch outside diameter used in NPT-threaded fluid systems operating within the rated pressure and temperature limits.

Installation Notes

Install by a licensed plumber or qualified technician in accordance with applicable plumbing codes such as the IPC. Shut off fluid supply and relieve system pressure before removing or installing any fitting. Apply appropriate thread sealant or PTFE tape to the NPT threads before tightening; do not overtighten polypropylene fittings as the material can crack. Secure tubing to the barb with a compatible clamp to prevent pull-off under pressure.
