Parker 329HB-12-12PP Barbed Tube Male Elbow 3/4 in Npt

Product Description

The PARKER 329HB-12-12PP is a single-barb male elbow fitting designed to connect flexible tubing to a threaded male NPT port in a 90-degree configuration. Constructed from black polypropylene, this fitting accepts 3/4 inch inside diameter tubing and threads into a 3/4 inch NPT female port. It is rated for working pressures up to 125 psi and handles temperatures from 0 degrees F up to 212 degrees F, making it suitable for a wide range of fluid transfer applications. The fitting meets FDA Compliant and NSF/ANSI 51 standards, qualifying it for use in food equipment and potable water-contact environments where material safety is a regulatory requirement.

This elbow fitting is used in plumbing, HVAC, and fluid handling systems where a directional change is needed between a barbed tubing run and a threaded connection point. Common install scenarios include commercial food service equipment, water treatment systems, cooling and refrigeration fluid circuits, and potable water distribution assemblies. The 90-degree male elbow configuration is well suited for tight spaces where a straight fitting cannot make the turn without stressing the tubing.

Key Features

• Single-barb design secures 3/4 inch ID flexible tubing without additional hardware
• 3/4 inch NPT male thread for direct installation into female NPT ports
• Polypropylene construction resists corrosion and chemical degradation in fluid service
• Rated to 125 psi maximum working pressure
• Operates from 0 degrees F to 212 degrees F (-12.2 degrees C to 100 degrees C)
• FDA Compliant and NSF/ANSI 51 certified for food equipment and potable water contact

Compatibility

Designed as an OEM-style replacement or new-installation fitting for flexible tubing systems using 3/4 inch inside diameter tubing with 3/4 inch NPT threaded ports in plumbing and fluid transfer applications.

Installation Notes

Installation is typically performed by licensed plumbers or qualified fluid system technicians. Shut off and relieve pressure from the fluid circuit before removing any existing fittings or making new connections. Apply thread sealant or PTFE tape to the male NPT threads in accordance with IPC guidelines before threading into the receiving port. Secure tubing onto the barb with an appropriate clamp to maintain a leak-free seal under working pressure.
