Description
150# Galvanized Malleable Iron Hex Bushing
150# galvanized malleable iron hex bushings reduce a larger female-threaded opening to a smaller female NPT connection. The male NPT exterior threads install into a larger fitting, valve, manifold, or equipment port, while the internal female NPT threads accept a smaller male-threaded pipe, nipple, valve, or accessory.
Select the required size combination from the product options above. Variations are listed as male connection × reduced female connection. The selected variation determines the Charman item number, online selling price, weight, cost, and other size-specific product information.

How a Hex Bushing Works
The larger male NPT threads install into a compatible female-threaded opening. The smaller internal female NPT connection then accepts a reduced-size male-threaded pipe, pipe nipple, valve, gauge, or accessory. The external hex shape allows the fitting to be tightened with a suitable wrench.

Frequently Asked Questions
What is a galvanized hex bushing used for?
A hex bushing reduces a larger female-threaded opening to a smaller female NPT connection.
Which size is listed first?
The larger male NPT connection is listed first, followed by the smaller female NPT connection.
Why does the fitting have a hex-shaped body?
The hex body provides wrench flats so the bushing can be installed and removed with a suitable wrench.
What pressure class is this fitting?
This galvanized malleable iron hex bushing is manufactured as a 150# or Class 150 threaded fitting.
Can this bushing be used with galvanized steel pipe and fittings?
Yes. It is designed for compatible NPT-threaded galvanized pipe, fittings, valves, gauges, equipment ports, and other approved components.
Does the galvanized finish improve corrosion resistance?
Yes. The galvanized finish provides added corrosion resistance compared with an unfinished black fitting, although suitability still depends on the environment, media, temperature, and application.
Can it be used for water, air, oil, gas, or steam?
It may be used in compatible water, compressed-air, oil, gas, steam, and general-service systems when the application remains within applicable pressure, temperature, media, code, and manufacturer requirements.
Should thread sealant be used?
Use an approved pipe-thread sealant or thread tape on the applicable male NPT connections, selected for the piping media, pressure, temperature, applicable codes, and manufacturer recommendations.
Important Ordering Notes
- Select the exact size combination before adding the product to your cart.
- The selected variation determines the Charman item number, price, weight, and cost.
- Variations are listed as male connection x reduced female connection.
- Confirm both nominal sizes and thread types before ordering.
- Use the hex wrench flats for installation; do not apply force to unsupported areas of the fitting.
- Use an approved thread sealant suitable for the piping media and operating conditions.
- Do not overtighten the fitting, as excessive force can damage the threads or fitting body.
- Confirm pressure, temperature, media compatibility, corrosion exposure, and application requirements before installation.
- Installation should be completed by qualified personnel and comply with applicable codes and standards.
- Manufacturer warranty coverage is subject to the terms, limitations, and exclusions in the linked warranty document.
