Parker 329HB-8-4N Barbed Tube Male Elbow 1/2 in Barb 1/4 Npt

Product Description

The PARKER 329HB-8-4N is a barbed tube male elbow fitting designed to connect flexible tubing to a male NPT-threaded port at a 90-degree angle. It features a 1/2 inch barb for secure tubing retention and a 1/4 inch NPT male thread for direct installation into a female-threaded fitting, valve, or manifold port. Constructed from white nylon, this fitting is lightweight, corrosion-resistant, and suited for low-pressure fluid and air transfer applications. Licensed plumbers, HVAC technicians, and fluid-handling professionals install this type of fitting in systems where a directional change is needed between a barbed tubing run and a threaded connection point.

This elbow fitting is used in residential and light commercial applications including HVAC condensate drain lines, pneumatic tubing systems, water treatment equipment, and general fluid transfer setups. The 90-degree male elbow configuration is well suited for tight routing situations where straight fittings would require excessive bend radius in the connected tubing. Nylon construction makes it appropriate for use with compatible non-aggressive fluids and compressed air within the fitting's rated conditions.

Key Features

• 1/2 inch barb size for secure push-and-clamp tubing retention
• 1/4 inch NPT male thread for direct installation into female NPT ports
• 90-degree elbow geometry allows directional routing in confined spaces
• Nylon construction provides corrosion resistance and light weight
• White color for easy visual identification in fluid handling systems

Compatibility

Designed as an OEM-style barbed tube fitting for use with flexible tubing sized to accept a 1/2 inch barb and systems with 1/4 inch NPT female-threaded ports.

Installation Notes

This fitting is typically installed by licensed plumbers or HVAC technicians during new installation or service of fluid and air handling systems. Shut off system pressure before removing or installing any fitting. Hand-tighten the NPT thread first, then apply wrench tightening per applicable plumbing or pneumatic system guidelines, taking care not to overtighten nylon threads. Secure the barbed end with an appropriate clamp or ensure tubing is rated for the intended operating pressure and fluid type.
