Asc Engineered Solutions 1BXE.NB Hex Head Pipe Bushing 1-1/4x3/4

Product Description

The ASC Engineered Solutions 1BXE.NB is a galvanized cast iron hex head pipe bushing used to reduce a larger female-threaded port down to a smaller male-threaded pipe connection. Sized at 1-1/4 x 3/4 inch nominal, it features a male NPT (MNPT) outer thread and a female NPT (FNPT) inner thread. Rated at 125 lb, this bushing is manufactured domestically and carries the corrosion protection of a galvanized finish. Plumbers and pipefitters install this fitting when transitioning between pipe sizes in threaded iron or steel piping systems.

This bushing is suited for residential and light commercial plumbing, gas distribution, and hydronic heating applications where a threaded size reduction is required at a tee, valve, or fitting port. The hex head profile provides secure wrench engagement during installation and removal, reducing the risk of slippage on the fitting body. It is appropriate for use in dry, wet, and low-pressure gas piping systems within the pressure limits of a 125 lb rated cast iron fitting.

Key Features

• 1-1/4 x 3/4 inch nominal size reduction in a single fitting
• MNPT outer thread x FNPT inner thread configuration
• 125 lb pressure class cast iron construction
• Galvanized finish for corrosion resistance in exposed or damp environments
• Hex head profile for positive wrench engagement
• Domestically manufactured

Compatibility

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

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable codes such as the IPC or IFGC. Shut off and depressurize the piping system fully before threading or unthreading any fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before installation. Do not over-tighten; use a pipe wrench on the hex head only and follow standard NPT engagement practice for cast iron fittings.
