Description
300# Extra Heavy Galvanized Malleable Iron Reducer
300# extra heavy galvanized malleable iron reducers connect two different nominal pipe sizes in a straight threaded piping run. The larger and smaller female NPT openings provide a durable size transition for demanding commercial, industrial, mechanical, fire-protection, maintenance, and repair applications where corrosion resistance and a galvanized finish are required.
Select the required size configuration from the product options above. Sizes are listed as large end x small end. The selected variation determines the ASC item number, online selling price, estimated weight, net cost, and other configuration-specific product information.

How a Threaded Reducer Works
A threaded reducer has two female NPT openings of different nominal sizes aligned in a straight line. The larger opening connects to a compatible larger male-threaded pipe, pipe nipple, valve, or fitting, while the smaller opening connects to the reduced-size component, creating a secure transition between pipe sizes.
