BMI Bushing Pipe Fitting with NPT Threads for Plumbing Systems

Overview

 Black Malleable Iron Hex Bushing (Fig. 241)

Black malleable iron threaded hex bushings (Fig. 241) are designed to reduce pipe size and connect threaded pipes or fittings of different diameters in piping systems. Manufactured from high-quality malleable iron, these bushings offer excellent mechanical strength, durability, and resistance to impact and pressure.

Available in sizes from 1/8" to 6" (DN6–DN150), the fittings comply with major international standards including EN 10242, ASME B16.3, DIN 2950, ISO 49, BS EN 10242, and other equivalent specifications. Threading is produced in accordance with EN 10226, ASME B1.20.1, DIN 2999, ISO 7-1, ISO 228, ensuring tight, leak-free connections and full interchangeability with global piping systems.

Designed for working pressures up to PN25 / 25 Bar (2.5 MPa, Class 150), black malleable iron hex bushings are suitable for water supply, fire protection, gas, oil, and general industrial applications.

The products are UL Listed and FM Approved, and also comply with CE, ABNT, TSE, SNI, and ISI certifications, meeting the requirements of international projects and regulated markets worldwide.

Product Description

A threaded bushing (also known as a reducing or hex bushing) is a piping fitting designed to connect pipes or fittings of different diameters within a threaded piping system. It typically features male threads on one end and female threads on the other, allowing a smooth and reliable transition between different pipe sizes. Bushings are widely used in water supply, fire protection, gas, HVAC, and industrial piping systems.

Key Features

• Size reduction function: Enables efficient connection between pipes of different nominal diameters without changing the pipeline layout

• Male × female threaded design: Manufactured with standard threads to ensure tight, leak-free connections

• Compact and robust structure: High mechanical strength with excellent resistance to pressure and impact

• Easy installation: Simple threaded connection allows quick assembly and convenient maintenance

• Wide compatibility: Suitable for use with valves, meters, pumps, and other threaded piping components

Functions & Applications

Threaded bushings are primarily used to reduce pipe size and connect internal and external threaded components in piping systems. They provide a reliable and economical solution for diameter conversion while maintaining system integrity and sealing performance.

Common applications include:

• Water supply and drainage systems

• Fire sprinkler and fire protection piping

• Gas and air pipelines

• HVAC systems

• General industrial fluid conveying systems
