Parker 325HB-10-6N Barbed Tube Male Connector 5/8 in Barb

Product Description

The PARKER 325HB-10-6N is a barbed tube male connector designed for fluid and air line connections in plumbing, HVAC, and industrial piping systems. It features a 5/8 inch barb on one end and a 3/8 inch NPT male thread on the other, allowing a secure transition from rigid or semi-rigid tubing to threaded fittings. Constructed from nylon, this connector offers lightweight corrosion resistance suited for low-pressure pneumatic and fluid transfer applications. Licensed plumbers, HVAC technicians, and pipefitters install this type of fitting where a permanent or semi-permanent barbed-to-threaded connection is required.

This connector is appropriate for residential and light commercial applications involving tubing runs connected to threaded ports on valves, manifolds, pumps, or equipment housings. The nylon construction makes it suitable for non-aggressive fluid service and compressed air lines operating within the material's rated pressure and temperature limits. It is commonly found in HVAC condensate drain lines, water treatment plumbing, and irrigation system branch connections where a barb-to-NPT male transition fitting is needed.

Key Features

• 5/8 inch barb accommodates standard barbed tubing connections
• 3/8 inch NPT male thread for direct engagement with female NPT ports
• Nylon construction provides corrosion resistance and light weight
• White color for easy identification in multi-line installations
• Compact form factor suitable for tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems requiring a 5/8 inch barb to 3/8 inch NPT male connector in nylon construction.

Installation Notes

Install and service by a licensed plumber or qualified HVAC technician in accordance with applicable IPC and IFGC guidelines. Shut off fluid supply and depressurize the line before installation or removal. Hand-tighten the NPT thread and apply appropriate thread sealant tape before final tightening — do not overtighten nylon fittings, as the material can crack under excessive torque. Ensure the barb end is fully seated and the tubing is secured with an appropriate clamp or retainer.
