Asc Engineered Solutions 6X5.NB Hex Head Pipe Bushing

Product Description

The ASC ENGINEERED SOLUTIONS 6X5.NB is a hex head pipe bushing designed to reduce a 6-inch male NPT connection down to a 5-inch female NPT connection. Cast from 125 lb class cast iron and finished with a galvanized coating for corrosion resistance, this bushing is built for demanding piping systems in commercial and industrial environments. The hex head profile allows for secure wrench engagement during installation. Domestically manufactured, it meets the material and pressure class expectations of professional piping work.

This bushing is used in plumbing, fire protection, and industrial piping applications where a reduction from a 6-inch to a 5-inch pipe connection is required. The MNPT x FNPT configuration makes it suitable for threaded pipe assemblies in both wet and dry systems. Plumbers and pipefitters working on large-diameter commercial or industrial runs will encounter this size in mechanical rooms, main distribution headers, and process piping installations.

Key Features

• 6-inch MNPT to 5-inch FNPT hex head reducing bushing
• 125 lb pressure class cast iron construction
• Galvanized finish for corrosion resistance in exposed or damp environments
• Hex head design provides secure wrench grip for proper torque
• Domestically manufactured to standard pipe fitting dimensions

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 125 lb threaded cast iron piping systems requiring a 6-inch to 5-inch reduction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and IFGC codes. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-torque cast iron fittings, as the material is not ductile and can crack under excessive force.
