Parker 329HB-3-2N Barbed Male Elbow 3/16 in Barb 1/8 Npt

Product Description

The PARKER 329HB-3-2N is a single-barb male elbow tube fitting designed to connect flexible tubing to a 1/8 inch NPT threaded port at a 90-degree angle. Made from white nylon, this fitting accepts tubing with a 3/16 inch inside diameter and a 0.25 inch outside diameter. It is rated for working pressures up to 125 psi and a temperature range of -40 degrees F to 200 degrees F. The fitting meets FDA compliance standards and NSF/ANSI 51 certification, making it suitable for applications requiring food-grade or potable-water-contact materials. Licensed plumbers, HVAC technicians, and equipment service professionals install this type of fitting in fluid-handling assemblies.

This fitting is used in light-duty fluid transfer applications across residential and commercial equipment, including beverage dispensing systems, water treatment equipment, HVAC condensate lines, and food-service machinery. The single-barb design provides a secure grip on compatible flexible tubing. Its NPT male thread allows direct connection into standard threaded ports on valves, manifolds, pumps, and equipment housings. The white nylon construction resists corrosion and keeps weight minimal in tight installations.

Installation Notes

Installation is performed by qualified plumbers or equipment technicians. Depressurize and drain the system completely before removing or installing any fittings. Apply thread sealant tape or compound to the NPT male threads before tightening to prevent leaks. Do not overtighten nylon fittings, as the material can crack under excessive torque; hand-tighten plus a moderate additional turn is the standard practice for plastic NPT fittings.
