Description
300# Extra Heavy Black Malleable Iron Bell Reducer
300# extra heavy black malleable iron bell reducers connect two different nominal pipe sizes in a threaded piping system. The female NPT x female NPT reducing configuration provides a compact transition from a larger pipe size to a smaller pipe size while maintaining a heavy-duty Class 300 malleable iron connection.

How a Bell Reducer Works
A threaded bell reducer has female NPT threads on both ends, with one opening sized for the larger pipe and the opposite opening sized for the smaller pipe. The bell-shaped body creates a compact transition between the two nominal pipe sizes. Each end accepts a compatible male-threaded pipe, nipple, valve, or fitting.

Frequently Asked Questions
What is a 300# black malleable iron bell reducer used for?
It connects two different nominal pipe sizes in a threaded piping system while providing female NPT connections on both ends.
What connections does this bell reducer have?
It has one larger female NPT connection and one smaller female NPT connection.
How is a bell reducer different from a reducing bushing?
A bell reducer has female NPT threads on both ends. A reducing bushing typically has a male NPT connection on the outside and a smaller female NPT connection on the inside.
What pressure class is this fitting?
This fitting is manufactured as a 300# / Class 300 extra heavy threaded malleable iron fitting.
What reducing sizes are available?
Available product variations range from 3/8" x 1/4" through 4" x 3" nominal pipe size combinations.
What standards and approvals apply?
The fitting conforms to ASME B16.3, ASTM A197, and ASME B1.20.1 requirements and is UL/ULC Listed and FM Approved.
Should thread sealant be used during installation?
Use an approved pipe-thread sealant or thread tape selected for the piping media, pressure, temperature, applicable codes, and manufacturer recommendations.
