Galvanized Malleable Iron Reducing Hex Bushing — Class 150, MNPT x FNPT
The galvanized reducing hex bushing lets you step a larger male NPT connection down to a smaller female NPT port in a single, compact fitting — ideal for adapting compressed-air lines, water, steam, oil, and gas piping to a different thread size. Cast from malleable iron and hot-dip galvanized for corrosion resistance, it installs with a wrench using the external hex and threads directly into matching NPT pipe, nipples, and fittings.
