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

Product Description

The PARKER 329HB-6-8N is a barbed tube male elbow fitting designed for low-pressure fluid and air transfer applications. It connects a 3/8 inch barbed tube to a 1/2 inch NPT male threaded port, creating a 90-degree directional change in the line. Constructed from nylon, this fitting is lightweight, corrosion-resistant, and suitable for use in non-aggressive fluid systems. The white color aids in visual identification during installation and inspection. Plumbers, HVAC technicians, and general mechanical contractors commonly install this type of fitting in equipment panels, condensate lines, and fluid distribution assemblies.

This fitting is suited for residential and light commercial applications where a barbed-to-threaded transition is needed at a 90-degree angle. Typical uses include condensate drain connections, water distribution manifolds, pneumatic tubing assemblies, and other low-pressure piping systems that use flexible tubing on the barbed end and NPT-threaded ports on equipment housings or valves. The nylon construction makes it appropriate for fresh water, air, and mildly corrosive fluid service where metal fittings are not required.

Key Features

• 90-degree male elbow configuration for directional routing of tubing lines
• 3/8 inch barb end accepts standard flexible tubing for a secure push-on connection
• 1/2 inch NPT male thread for direct connection to female NPT ports on equipment
• Nylon construction provides corrosion resistance and low weight
• White color finish for easy visual identification in multi-line assemblies

Compatibility

Designed as an OEM-style replacement or new-installation barbed male elbow fitting for systems using 3/8 inch flexible tubing and 1/2 inch NPT female-threaded ports in low-pressure fluid or air service.

Installation Notes

This fitting is installed by plumbers, HVAC technicians, and mechanical contractors working on low-pressure fluid or pneumatic systems. Shut off the fluid or air supply and depressurize the line before installation or removal. Thread the NPT end into the female port by hand first, then tighten with an appropriate wrench, applying thread sealant tape to the male threads per IPC guidelines. Secure the flexible tubing over the barb and use an appropriate clamp where required by the application or local code.
