What is a Bushing in Plumbing?

In the world of plumbing and piping, every small component plays a critical role in ensuring leak-free and secure fluid flow. One such important but often overlooked component is the bushing. Whether used in residential plumbing or industrial piping systems, bushings help connect pipes of different sizes and specifications with accuracy and strength.

At AB Steel, we are a leading manufacturer and exporter of ANSI/ASME B16.11 Forged Bushings β€” trusted worldwide for quality and durability. This blog explains what a plumbing bushing is, its uses, types, and importance in modern piping systems.

πŸ”© What is a Bushing in Plumbing?

A bushing in plumbing is a type of pipe fitting used to join two pipes of different diameters. It reduces the size of the opening in a pipe fitting to allow connection with a smaller pipe. Most bushings are threaded, allowing for a secure and pressure-tight connection.

βœ… Purpose of a Plumbing Bushing:

  • Size Reduction – Connects larger pipes to smaller ones
  • Flow Control – Helps manage pressure and flow transitions
  • Space Saving – Compact design ideal for tight installations
  • Leak Prevention – Offers strong and sealed connections

πŸ› οΈ Where Are Bushings Used?

Bushings are used across various sectors, including:

  • Plumbing and HVAC systems
  • Oil & Gas pipelines
  • Power generation and nuclear plants
  • Petrochemical industries
  • Water treatment and distribution systems

They are essential in both high- and low-pressure applications, especially where compactness and precision are crucial.
