Parker 325HB-6-12N Barbed Tube Male Connector 3/8 Barb

Product Description

The PARKER 325HB-6-12N is a single-barb male tube connector designed to join 3/8-inch ID flexible tubing to a 3/4-inch NPT male threaded port. Molded from white nylon, this fitting is rated for pressures up to 125 psi and a maximum working temperature of 200 degrees F, making it suitable for a broad range of low-pressure fluid transfer applications. The single-barb design grips tubing securely on assembly and resists pull-out under normal working pressures. At 1.72 inches in overall length and 0.01 pounds, it is a lightweight, corrosion-resistant alternative to brass fittings in compatible service conditions. Licensed plumbers and HVAC technicians commonly install this fitting in potable water, food-processing, and equipment plumbing lines.

This connector is used in residential and light commercial plumbing, HVAC condensate drainage, food and beverage equipment, and water filtration systems where FDA-compliant and NSF/ANSI 51-listed wetted components are required. The 3/8-inch barb accepts standard 3/8-inch ID flexible tubing, and the 3/4-inch NPT male thread mates to standard female NPT ports on valves, manifolds, or equipment housings. It is well suited for installations where nylon's chemical resistance and light weight are preferred over metal fittings.

Key Features

• Single-barb design for secure tubing retention on 3/8-inch ID flexible tubing
• 3/4-inch NPT male thread for connection to standard female NPT ports
• Nylon construction — corrosion resistant and lightweight at 0.01 pounds
• Rated to 125 psi maximum working pressure
• Temperature range: -40 degrees F to 200 degrees F
• FDA Compliant and NSF/ANSI 51 listed for food-zone and potable water service

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 3/8-inch ID flexible tubing with 3/4-inch NPT female threaded ports in plumbing, HVAC, and food-service equipment applications.

Installation Notes

Install by a licensed plumber or qualified technician in accordance with applicable IPC and local plumbing codes. Shut off and depressurize the water or fluid supply before removing or installing any fittings. Push tubing fully onto the barb past the barb bead to ensure a secure seal; hose clamps may be added where vibration or elevated pressure is a concern. Do not over-torque the NPT thread — hand-tight plus a modest fraction of a turn with a wrench is sufficient for nylon fittings to avoid cracking the fitting body.
