Parker 325HB-6-8PP Barbed Male Connector 3/8 Barb 1/2 Npt

Product Description

The PARKER 325HB-6-8PP is a single-barb male tube connector designed to join 3/8-inch ID flexible tubing to a 1/2-inch NPT male threaded port. Molded from black polypropylene, it handles working pressures up to 125 psi and temperatures from 0 degrees F to 212 degrees F. At 1.73 inches in overall length and weighing approximately 0.01 pounds, this fitting is compact and lightweight. It carries FDA Compliant and NSF/ANSI 51 certifications, making it suitable for food-equipment and potable-water applications where material compliance is required. Plumbers, HVAC technicians, and equipment service technicians install this fitting in fluid-handling assemblies that use push-on or barbed flexible tubing.

This connector is used in residential and light commercial plumbing, food service equipment, water treatment systems, and HVAC condensate or fluid-transfer lines where a threaded NPT port must transition to flexible tubing. The single-barb design grips tubing with an inside diameter of 3/8 inches and an outside diameter of 0.43 inches. It is well suited for low-to-moderate pressure water, air, or compatible fluid service within its rated temperature and pressure range. Applications that require NSF/ANSI 51 food-equipment compliance will find this fitting appropriate for use in those regulated assemblies.

Key Features

• Single-barb design secures 3/8-inch ID flexible tubing without tools or clamps in low-pressure service
• 1/2-inch NPT male thread provides a standard connection to pipe fittings, valves, and equipment ports
• Polypropylene construction resists corrosion and is compatible with a wide range of water and mild chemical services
• Rated to 125 psi maximum working pressure and 212 degrees F maximum working temperature
• FDA Compliant and NSF/ANSI 51 certified for use in food-equipment fluid-handling systems
• Compact at 1.73 inches overall length, fitting in tight equipment enclosures

Compatibility

Designed as an OEM-style replacement or service fitting for flexible-tubing assemblies requiring a 3/8-inch single-barb inlet and a 1/2-inch NPT male outlet in polypropylene construction.

Installation Notes

Installation is performed by a licensed plumber or qualified service technician. Shut off all fluid supply and relieve system pressure before removing or installing any fitting. Thread the NPT end into the receiving port by hand first, then tighten with an appropriate wrench using thread sealant tape or compound suitable for the service fluid. Push the compatible tubing fully onto the barb and verify seating before restoring pressure; a hose clamp is recommended when vibration or elevated pressure is present.
