BSP Threaded Reducing Bushes
Easily adapt and connect pipelines of different sizes with our high-quality BSP Threaded Reducing Bushes. These essential poly fittings feature a larger male thread on the outside and a smaller female thread on the inside, allowing you to neatly and efficiently reduce a threaded connection point.

What are BSP Threaded Reducing Bushes used for?

A BSP Reducing Bush is designed to connect two pipes or fittings of different diameters. It screws into a larger female fitting (such as a tee or elbow) to create a smaller female-threaded outlet.

Common Applications:

  • Irrigation Systems: Adapting a large manifold to feed smaller sprinkler lines.

  • Pumps & Valves: Reducing the inlet or outlet size of a pump to match existing pipework.

  • Industrial Piping: Creating compact size reductions in instrument lines or chemical dosing systems.

Key Features & Specifications

Manufactured for durability and precision, our reducing bushes provide a reliable, leak-resistant seal in a wide range of applications.

  • Material: High-grade, durable polypropylene for chemical and corrosion resistance.

  • Thread Type: BSP (British Standard Pipe) tapered male thread and parallel female thread for a secure seal.

  • Size Range: Comprehensive range from 3/4” x 1/2” up to 4” x 3” to suit virtually any project requirement.

  • Pressure Rating: Suitable for low-to-medium pressure applications (Check specific product ratings for details).

Note: We recommend using thread seal tape (PTFE tape) or a suitable thread sealant on all BSP threaded connections to ensure a watertight seal.
