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

Product Description

The PARKER 329HB-6-2PP is a barbed tube male elbow fitting designed to create a 90-degree connection between flexible tubing and a threaded port. Constructed from polypropylene, this black fitting accepts 3/8 inch barbed tubing on one end and threads into a 1/8 inch NPT male port on the other. The barbed design provides a secure, friction-held connection that resists pull-out when tubing is properly seated. This type of fitting is commonly installed by HVAC technicians, plumbers, and industrial service professionals working with low-pressure fluid or air lines where a directional change is needed at a threaded port.

This fitting is suited for residential and light commercial applications involving flexible tubing runs where a 90-degree transition to a threaded connection is required. Typical install scenarios include condensate drainage lines, water treatment equipment, pneumatic control lines, and similar low-pressure fluid systems. The 1/8 inch NPT male thread is a common port size found on solenoid valves, pressure switches, manifolds, and control components throughout HVAC and plumbing systems.

Key Features

• 3/8 inch barb size provides a secure grip on standard flexible tubing
• 1/8 inch NPT male thread for direct installation into female NPT ports
• Polypropylene construction offers resistance to moisture and many common chemicals
• 90-degree elbow orientation reduces stress on tubing at tight-clearance connection points
• Black color for straightforward identification in mixed-fitting installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with 3/8 inch flexible tubing and female 1/8 inch NPT threaded ports in low-pressure fluid and pneumatic applications.

Installation Notes

Installation is typically performed by licensed HVAC technicians or plumbers. Shut off fluid or air supply and relieve system pressure before installing or replacing any fitting. Hand-tighten the NPT thread first, then use a wrench for final seating — avoid overtightening polypropylene threads. Seat the tubing fully over the barb and secure with an appropriate clamp or tie where required by system design or local codes.
