Parker 325HB-6-6PP Barbed Male Connector 3/8 in Npt

Product Description

The PARKER 325HB-6-6PP is a single-barb male tube connector designed for secure, low-pressure fluid line connections in plumbing, HVAC, and food-service equipment applications. Molded from polypropylene, this fitting accepts 3/8-inch inside diameter tubing and terminates with a 3/8-inch NPT male thread. It handles working pressures up to 125 psi and operating temperatures from 0 degrees F to 212 degrees F. The barbed end grips tubing without additional hardware, and the NPT thread seals into standard threaded ports with thread sealant or PTFE tape. At 1.61 inches overall length, it fits in compact manifold and equipment enclosure installations.

This connector is suited for residential and light commercial applications involving potable water, food-processing lines, or beverage-equipment plumbing where FDA Compliant and NSF/ANSI 51 certification is required. Plumbers, HVAC technicians, and equipment service professionals install this fitting in ice machines, water treatment systems, fluid transfer assemblies, and similar tubing runs that terminate at NPT-threaded ports. The black polypropylene construction resists corrosion and is compatible with a broad range of non-aggressive fluid media.

Key Features

• Single-barb design secures 3/8-inch ID tubing without clamps in low-pressure service
• 3/8-inch NPT male thread for direct connection to standard threaded ports
• Polypropylene construction resists corrosion and chemical degradation
• Rated to 125 psi maximum working pressure
• Temperature range from 0 degrees F to 212 degrees F suits hot and cold fluid lines
• FDA Compliant and NSF/ANSI 51 certified for potable water and food-equipment use

Compatibility

Designed as an OEM-style replacement or new-installation fitting for tubing systems using 3/8-inch ID tubing and 3/8-inch NPT threaded ports in plumbing, HVAC, and food-service equipment assemblies.

Installation Notes

Installation is typically performed by licensed plumbers or qualified HVAC or equipment service technicians. Shut off the fluid supply and depressurize the line before disassembly or fitting installation. Apply PTFE tape or an approved thread sealant to the NPT male threads before making up the connection; hand-tighten and then snug with a wrench to avoid cracking the polypropylene body. Push tubing fully onto the barb until it seats against the fitting shoulder, and verify the joint is leak-free before returning the system to service.
