Parker 325HB-12-12N Barbed Tube Male Connector 3/4 Npt

Product Description

The PARKER 325HB-12-12N is a single-barb male connector fitting designed for joining flexible tubing to threaded pipe or equipment ports. Molded from nylon and rated for continuous service from -40 degrees F to 200 degrees F, this fitting handles pressures up to 125 psi. The 3/4 inch barb accepts tubing with a 3/4 inch inside diameter and a 0.8 inch outside diameter, while the 3/4 inch NPT male thread connects to standard taper-threaded ports. It is FDA compliant and certified to NSF/ANSI 51, making it suitable for food-equipment and potable-water fluid-handling applications. Plumbers, HVAC technicians, and equipment service technicians install this fitting in low-pressure fluid lines where a secure barb-to-thread transition is required.

This connector is used in residential and light commercial fluid-handling systems where flexible tubing must terminate at a threaded male connection. Typical applications include water treatment equipment, food-service machinery, HVAC condensate lines, and other systems requiring NSF/ANSI 51 or FDA-compliant components. The white nylon construction resists corrosion and is compatible with a range of water-based fluids. Its compact overall length of 1.85 inches makes it well suited for tight installations with limited clearance around fittings.

Compatibility

Designed as an OEM-style replacement or service fitting for flexible-tubing systems using 3/4 inch ID tubing and 3/4 inch NPT threaded ports in plumbing, HVAC, and food-service fluid-handling applications.

Installation Notes

Installation is typically performed by a licensed plumber or qualified HVAC technician following applicable IPC or local plumbing code requirements. Shut off fluid supply and relieve line pressure before removing or installing any fitting. Apply thread sealant tape or compound to the NPT threads before tightening; do not over-tighten nylon fittings, as the material can crack under excessive torque. Confirm tubing is fully seated past the barb and secure with an appropriate clamp before restoring pressure.
