The ASC ENGINEERED SOLUTIONS 319907127 is a galvanized hex bushing designed to reduce pipe thread sizes in iron pipe systems. It transitions from a 1-1/4 inch male NPT thread to a 1/2 inch female NPT thread, allowing plumbers and pipefitters to connect pipes or fittings of different diameters without additional adapters. The galvanized iron construction provides corrosion resistance suited for water distribution, gas, and general plumbing applications. At 0.35 pounds, this is a compact fitting that installs quickly with standard pipe wrenches. Domestic manufacturing ensures consistent thread tolerances that meet industry standards.
This hex bushing is used in residential and light commercial plumbing systems wherever a pipe size reduction is needed in an iron pipe run. Typical applications include water supply lines, compressed air distribution, and gas piping assemblies. The hex profile on the outer body allows wrench engagement for proper torque without slippage, making it practical for tight spaces where a standard coupling and reducer combination would not fit. Plumbers and mechanical contractors commonly stock this fitting for service calls and new construction rough-in work alike.
Designed as an OEM-style replacement or standard service fitting for 1-1/4 inch to 1/2 inch iron pipe thread systems in residential and commercial plumbing and mechanical applications.
Installation should be performed by a licensed plumber or qualified pipefitter in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the pipe system fully before removing any existing fittings or threading in the new bushing. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten iron fittings, as excess force can crack the fitting body or damage threads.
