The ASC ENGINEERED SOLUTIONS 319905568 is a galvanized steel threaded hex bushing designed to reduce pipe thread sizes in plumbing, HVAC, and mechanical piping systems. It features a 1/2 inch female NPT inlet and a 1/8 inch male NPT outlet, allowing technicians to step down pipe sizes within a threaded assembly. The galvanized steel construction resists corrosion, making it suitable for use in moderate-moisture environments. Weighing 0.11 pounds, this compact fitting is a standard component stocked by plumbers, pipefitters, and HVAC mechanics for field and shop work.
This hex bushing is used wherever a threaded pipe reduction is needed between 1/2 inch and 1/8 inch connections. Common applications include gas distribution manifolds, compressed air lines, water supply systems, and HVAC equipment piping. The hex profile allows a wrench to apply proper torque during installation without damaging the fitting body. It is appropriate for both residential and light commercial mechanical systems requiring a reliable, low-cost threaded reducer.
Designed as a standard NPT threaded hex bushing for use in residential and light commercial plumbing, HVAC, and mechanical piping systems requiring a 1/2 inch to 1/8 inch pipe thread reduction.
Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes and the International Plumbing Code or International Fuel Gas Code where relevant. Shut off and depressurize the piping system before removing or installing any threaded fittings. Apply thread sealant tape or compound rated for the intended service medium to the male threads before assembly. Use a properly sized wrench on the hex body to tighten the fitting — do not over-tighten, as this can crack or distort fittings downstream.
