This thread reducer or straight bush from RS PRO is a pipe fitting with threads on the inside and on the outside. It provides an easy way to link two pipes or other fittings of different sizes.


For effective resistance to corrosion, mechanical damage and heat, the body is made of robust stainless steel. It's suitable for high-pressure applications thanks to its male and female tapered threads. The hexagonal-shaped head makes it easy to tighten using a wrench.


This reducing bush complies with the Restriction of Hazardous Substances (RoHS) requirements and contains only negligible amounts of any harmful materials. It also meets the ASTM (American Society for Testing and Materials) B16.11 specifications for fittings and pipework. This type of stainless steel reducer is commonly used in heating and water systems in domestic and industrial settings.
