Asc Engineered Solutions 1DXE.NB Hex Head Pipe Bushing

Product Description

The ASC Engineered Solutions 1DXE.NB is a galvanized cast iron hex head pipe bushing used to reduce a larger female-threaded pipe opening to a smaller male-threaded connection. With a nominal size of 1-1/2 x 3/4 inches and an MNPT x FNPT end configuration, it provides a secure, leak-resistant threaded transition in low-pressure piping systems. Rated at 125 lb, this bushing is a standard fitting for gas, water, and industrial piping applications. It is installed by licensed plumbers and pipefitters as part of routine system assembly or repair.

This bushing is suited for residential and light commercial piping systems where a threaded size reduction is required between pipe segments or at equipment connections. The galvanized finish provides corrosion resistance for use in exposed or damp environments. The hex head design allows for secure wrench engagement during installation, making it appropriate for tight quarters where torque control matters. It is commonly used in water supply, gas distribution, and general-purpose industrial piping configurations.

Key Features

• Hex head design allows full wrench engagement for secure tightening
• MNPT x FNPT thread configuration for male-to-female threaded pipe reduction
• Nominal size 1-1/2 x 3/4 inches for reducing pipe diameter at connections
• 125 lb pressure rating suitable for standard low-pressure piping service
• Galvanized cast iron construction provides corrosion resistance in damp or exposed environments
• Domestic manufacture

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 125 lb threaded cast iron piping systems using NPT connections.

Installation Notes

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