Parker 329HB-4-8PP Barbed Male Elbow 1/4 Barb 1/2 Npt

Product Description

The PARKER 329HB-4-8PP is a barbed tube male elbow fitting designed to connect flexible tubing to a male NPT threaded port in a 90-degree configuration. The barb accepts 1/4 inch tubing and threads into a 1/2 inch NPT female port. Constructed from polypropylene, this fitting offers good chemical resistance and is suited for low-pressure fluid transfer, pneumatic tubing runs, and plumbing drainage or supply applications. The black color aids in system identification. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this type of fitting in both residential and light commercial settings.

This fitting is appropriate for use in fluid transfer lines, condensate drain systems, chemical feed lines, and general-purpose pneumatic or liquid tubing assemblies where a directional change from flexible tubing to a threaded port is required. The male NPT thread allows direct installation into a female-threaded valve, manifold, reservoir, or bulkhead. Polypropylene construction makes it a practical choice in environments where mild chemical exposure or moisture is present.

Key Features

• 1/4 inch barb accepts standard flexible tubing for a secure push-on grip
• 1/2 inch male NPT thread for direct connection to female-threaded ports
• 90-degree elbow configuration allows directional routing without separate fittings
• Polypropylene construction provides lightweight chemical resistance
• Black finish supports system color-coding or visual differentiation

Compatibility

Designed as an OEM-style replacement or standard-service barbed male elbow for systems using 1/4 inch flexible tubing terminating at a 1/2 inch NPT female port.

Installation Notes

Shut off fluid or air supply and relieve system pressure before removing or installing any fitting. Apply appropriate thread sealant or PTFE tape to the male NPT threads before installation and tighten to hand-snug plus a moderate turn — do not overtighten polypropylene fittings, as over-torquing can crack the body. Ensure the barbed tubing is fully seated past the barb retaining ridge for a leak-free connection. This type of fitting is typically installed by licensed plumbers or qualified HVAC technicians in accordance with applicable IPC or local mechanical code requirements.
