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

Product Description

The PARKER 325HB-10-8N is a single-barb male tube connector designed to join flexible tubing to a 1/2 inch NPT male thread. Molded from white nylon, it accepts tubing with a 5/8 inch inside diameter and a 0.66 inch outside diameter. The fitting is rated for working pressures up to 125 psi and handles temperatures from -40 degrees F to 200 degrees F, making it suitable for a wide range of fluid-handling and pneumatic applications. It carries FDA compliance and meets NSF/ANSI 51 standards for food-equipment materials. Plumbers, HVAC technicians, and industrial maintenance technicians install this fitting where a secure barbed-to-threaded transition is needed.

This connector is used in residential and light commercial plumbing, food and beverage equipment, water treatment systems, and HVAC fluid lines where flexible tubing must terminate at an NPT-threaded port. The NSF/ANSI 51 rating makes it appropriate for potable-water-adjacent and food-zone installations. Its nylon construction resists corrosion and keeps weight low, and the single-barb design allows for quick hand assembly onto compatible flexible tubing without specialized tooling.

Key Features

• Single-barb design for a secure, leak-resistant grip on 5/8 inch ID flexible tubing
• 1/2 inch NPT male thread for direct connection to standard NPT female ports
• Nylon construction resists corrosion and chemical attack in typical fluid-handling environments
• Rated to 125 psi maximum working pressure
• Operating temperature range of -40 degrees F to 200 degrees F
• FDA compliant and NSF/ANSI 51 certified for food-equipment and potable-water-adjacent use

Compatibility

Designed as an OEM-style barbed fitting for flexible tubing with a 5/8 inch inside diameter and a 0.66 inch outside diameter, terminating at any standard 1/2 inch NPT female-threaded port.

Installation Notes

Installation is typically performed by a licensed plumber or qualified HVAC technician. Shut off the water or fluid supply and relieve system pressure before making or breaking any fitting connection. Hand-tighten the NPT thread and apply an appropriate thread sealant or PTFE tape per IPC guidelines; do not overtighten nylon fittings, as excessive torque can crack the body. Secure the tubing fully onto the barb before placing the line under pressure, and verify there are no leaks before returning the system to service.
