Parker 325HB-6-2N Barbed Tube Male Connector 3/8 Inch

Product Description

The PARKER 325HB-6-2N is a single-barb male tube connector designed for low-pressure fluid and pneumatic line connections in trade and industrial applications. Molded from white nylon, this fitting accepts 3/8-inch tube ID with a 0.43-inch OD and threads into a 1/8-inch NPT male port. It measures 1.49 inches in overall length and weighs 0.01 pounds. Rated to 125 psi maximum working pressure, it handles temperatures from -40 degrees F to 200 degrees F, making it well-suited for food-grade, potable water, and light fluid system applications where corrosion resistance and compliance matter.

This connector is used in residential and commercial installations involving tubing runs for water treatment, food equipment, and HVAC-adjacent fluid handling systems. The 1/8-inch NPT thread connects directly to manifolds, valves, solenoids, and equipment ports. The single-barb design grips tubing securely for push-on assembly. Plumbers, HVAC technicians, and equipment service technicians encounter this fitting type in water filtration, beverage dispensing, and process fluid lines where nylon construction and certified compliance are required by specification.

• Compact 1.49-inch overall length suits tight installation spaces

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 3/8-inch ID tubing with 1/8-inch NPT male port connections in food equipment, water treatment, and light fluid handling applications.

Installation Notes

Installation is typically performed by licensed plumbers or qualified service technicians. Shut off and depressurize the fluid line before replacing or installing this fitting. Apply thread sealant or PTFE tape to the NPT threads in accordance with manufacturer and applicable plumbing code requirements. Do not over-tighten the NPT connection, as nylon fittings can crack under excessive torque; hand-tighten plus minimal wrench turns is the standard approach for plastic NPT fittings.
