Asc Engineered Solutions 318908928 Cast Iron Hex Bushing

Product Description

The ASC ENGINEERED SOLUTIONS 318908928 is a black cast iron hex bushing used to reduce pipe thread sizes in plumbing and mechanical piping systems. The bushing transitions from a 4-inch female thread to a 1-1/2-inch male thread, allowing trades to connect pipes of different diameters within the same run. At 3.05 pounds, the cast iron construction provides durability in both above-ground and in-wall applications. The hex body design gives wrenches a solid grip during installation, reducing the risk of joint damage during makeup. Licensed plumbers and pipefitters are the primary installers of this fitting in commercial and industrial settings.

This hex bushing is suited for use in black iron piping systems commonly found in gas distribution, fire protection, and industrial fluid lines. The 4-inch by 1-1/2-inch reduction ratio makes it a practical choice for branch takeoffs and outlet reductions where a significant size change is needed within a single threaded fitting. Domestically manufactured, it meets the dimensional expectations of standard NPT threaded systems.

Key Features

• Cast iron body provides strength and long service life in demanding piping environments
• Hex profile allows wrench engagement for controlled, accurate thread makeup
• Black coating finish compatible with black iron pipe systems
• 4-inch female to 1-1/2-inch male thread reduction in a single fitting
• Domestically manufactured

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded black iron pipe systems requiring a 4-inch to 1-1/2-inch concentric reduction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable codes such as the IPC or IFGC depending on the service fluid. Shut off and depressurize the piping system fully before threading or unthreading any fitting. Apply appropriate thread sealant or PTFE tape to the male threads before makeup. Do not overtighten; use the hex flats with a pipe wrench for controlled torque without damaging the casting.
