The ASC ENGINEERED SOLUTIONS 319908406 is a threaded galvanized hex bushing designed to reduce a 3-inch female pipe thread down to a 1-inch male pipe thread. Made from iron with a galvanized coating, this bushing provides corrosion resistance in standard plumbing and piping systems. The hex profile allows for proper torque application using a wrench during installation. Plumbers and pipefitters use this fitting to transition between pipe sizes without requiring additional unions or couplings. It is a domestically sourced component suited for threading directly into female-threaded fittings, tees, couplings, or valves in gas, water, and general fluid service applications.
This hex bushing is used in residential and commercial piping installations where a 3-inch line must be reduced to a 1-inch connection. Typical applications include distribution headers, supply manifolds, boiler piping, and mechanical room rough-in work. The galvanized iron construction makes it appropriate for use in moderately corrosive environments and is commonly found in water supply, gas distribution, and compressed air systems that use threaded iron pipe.
Designed as an OEM-style threaded replacement fitting for standard 3-inch by 1-inch iron pipe thread applications in residential and commercial plumbing and mechanical systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten; use a wrench on the hex body only and avoid applying force to connected pipe sections.
