The Screwed Brass Reducing Bush is a reliable brass fitting designed to reduce threaded connection sizes in fluid and gas systems. This fitting is ideal for connecting components with mismatched thread diameters in oil, fuel, water, natural gas, and lubrication lines.
Manufactured from high-quality brass, the reducing bush is available in both BSP and NPT thread types, making it suitable for both domestic and international applications. With a maximum pressure rating of 3500 kPa (500 PSI), it provides a secure and corrosion-resistant solution for system size transitions.
