Parker 325HB-5-6N Barbed Tube Male Connector 3/8 Npt

Product Description

The PARKER 325HB-5-6N is a single-barb male connector designed to join flexible tubing to a 3/8-inch NPT male-threaded port. Molded from white nylon, it accepts tubing with a 5/16-inch inside diameter and a 0.37-inch outside diameter. The 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 suitable for use in food-equipment and potable-water adjacent plumbing and fluid-transfer applications. Licensed plumbers, pipefitters, and equipment technicians install this fitting in light industrial, commercial food service, and fluid-handling system builds.

This connector is used wherever flexible nylon or polyethylene tubing must terminate at a threaded male NPT port. Typical applications include beverage dispensing equipment, food processing machinery, water filtration assemblies, and commercial plumbing systems that require a hygienic, corrosion-resistant fitting. The single-barb design provides a secure grip on compatible tubing when the tubing is pushed fully onto the barb and clamped or secured per system requirements. At 1.6 inches overall length, the fitting fits in confined equipment panels and manifold assemblies.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for flexible tubing systems using 5/16-inch ID tubing and 3/8-inch NPT threaded ports in food service, water filtration, and light industrial fluid-transfer equipment.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified equipment technicians. Depressurize and drain the fluid system completely before removing or installing any fitting. Apply thread sealant or PTFE tape to the NPT threads per the applicable plumbing code before threading into the port. Push flexible tubing fully onto the barb until it seats against the fitting shoulder, and secure with an appropriate clamp where system pressure or vibration requires it.
