Description
This PVCu threaded reducing bush is designed to reduce a BSP threaded connection from a larger size to a smaller size within an imperial pipe system. It screws into a larger BSP female outlet and provides a smaller BSP female thread, allowing valves, fittings or instruments with reduced threaded connections to be installed without changing the main pipework.
Manufactured from corrosion-resistant PVCu, the reducing bush delivers dependable long-term performance in water supply, industrial and general engineering applications. Its compact design provides a neat and efficient transition, while the precisely formed threads ensure secure mechanical joints when installed with a suitable thread sealant.
