Parker 325HB-12-12PP Barbed Tube Male Connector 3/4 in

Product Description

The PARKER 325HB-12-12PP is a single-barb male connector designed to join barbed tubing to a 3/4 inch NPT threaded port. Molded from black polypropylene, it accepts tubing with a 3/4 inch inside diameter and a 0.8 inch outside diameter. The fitting meets FDA compliance and NSF/ANSI 51 standards, making it suitable for food-equipment and potable-water-adjacent fluid handling applications. At 1.85 inches overall length and 0.01 pounds, it is a compact, lightweight component. Licensed plumbers, HVAC technicians, and equipment service professionals install this fitting in low-pressure fluid lines where a reliable barb-to-thread transition is needed.

This connector is used in residential and light commercial applications where polypropylene tubing must terminate at a threaded port. Typical install scenarios include water treatment equipment, food service machinery, HVAC condensate lines, and other fluid conveyance systems operating within its rated temperature and pressure range. The single-barb design secures tubing with a hose clamp for a leak-resistant connection at pressures up to 125 psi. Its NSF/ANSI 51 rating makes it a common choice where incidental food-contact compliance is required.

Installation Notes

Installation is typically performed by a licensed plumber or qualified equipment service technician. Shut off fluid flow and relieve system pressure completely before removing or installing any fitting. Apply thread sealant tape or compound to the NPT threads per the applicable plumbing code before tightening. Secure tubing over the barb with an appropriately sized hose clamp and inspect for leaks before returning the system to service.
