Parker 325HB-8-8N Barbed Male Connector 1/2 in Barb Npt Nylon

Product Description

The PARKER 325HB-8-8N is a single-barb male connector designed to join 1/2 inch ID flexible tubing to a 1/2 inch NPT male threaded port. Constructed from white nylon, this fitting is rated for working pressures up to 125 psi and a temperature range of -40 degrees F to 200 degrees F. It meets FDA compliance requirements and NSF/ANSI 51 standards, making it appropriate for food-equipment and potable-water-adjacent applications. The overall length is 1.73 inches. Plumbers, HVAC technicians, and equipment service professionals working on fluid-handling systems install this fitting where a quick, leak-resistant barbed connection to a threaded port is required.

This connector is suited for light- to medium-duty fluid transfer applications in residential and light commercial settings. Typical uses include potable water lines, food-service equipment plumbing, and low-pressure tubing runs in HVAC condensate or refrigeration drain systems. The single-barb design seats securely into flexible tubing with an inside diameter of 1/2 inch and an outside diameter of 0.55 inches. Its NSF/ANSI 51 listing makes it a correct choice wherever food-zone compliance is a project requirement.

Key Features

• Single-barb design provides a secure grip on 1/2 inch ID flexible tubing
• 1/2 inch NPT male thread for direct connection to standard threaded ports
• Nylon construction resists corrosion and is compatible with a wide range of non-aggressive fluids
• Rated to 125 psi maximum working pressure
• Operating range of -40 degrees F to 200 degrees F (-40 degrees C to 93.3 degrees C)
• FDA compliant and NSF/ANSI 51 listed for food-equipment applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch ID flexible tubing systems with 1/2 inch NPT threaded ports in food-service equipment, potable water systems, and low-pressure fluid transfer lines meeting NSF/ANSI 51 requirements.

Installation Notes

Installation is performed by licensed plumbers or qualified service technicians. Shut off and depressurize the fluid system completely before removing or installing any fittings. Apply thread sealant or PTFE tape to the NPT male threads per IPC guidelines before threading into the receiving port. Push the barbed end firmly into the tubing until the tubing seats past the barb, and secure with an appropriate hose clamp to prevent pull-off under pressure.
