Description
150# Galvanized Malleable Iron Extension Piece
150# galvanized malleable iron extension pieces extend an existing female-threaded outlet while maintaining the same nominal pipe size. The male NPT inlet threads into a compatible female opening, and the female NPT outlet provides a new threaded connection farther from the original fitting, valve, wall, or equipment surface.
Select the required nominal pipe size from the product options above. The selected variation determines the Charman item number, online selling price, weight, cost, and other size-specific product information.

How an Extension Piece Works
The male NPT end threads into a compatible female-threaded opening. The opposite female NPT end creates a same-size connection farther away from the original outlet, helping provide clearance for valves, gauges, pipe nipples, trim, equipment, or other threaded components.

Frequently Asked Questions
What is a galvanized malleable iron extension piece used for?
It extends an existing female-threaded outlet while providing a new female-threaded connection of the same nominal pipe size.
What thread configuration does it have?
It has one male NPT connection and one equal-size female NPT connection.
Does an extension piece change the pipe size?
No. These extension pieces maintain the same nominal pipe size from the male inlet to the female outlet.
What pressure class is this fitting?
This galvanized malleable iron extension piece is manufactured as a 150# or Class 150 threaded fitting.
What sizes are available?
Available product variations are 1/2", 3/4", and 1" nominal pipe size.
Can it be used with galvanized pipe fittings?
Yes. It is designed for compatible NPT-threaded galvanized pipe fittings, valves, pipe nipples, equipment, 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, piping media, temperature, and application.
Should thread sealant be used?
Use an approved pipe-thread sealant or thread tape on the male NPT connection, selected for the piping media, pressure, temperature, applicable codes, and manufacturer recommendations.
