CONCENTRIC REDUCERS ANSI B 16.9
 

With the aim to satisfactorily cater to the clients' requirements, we manufacture and export superior quality concentric reducers. Fabricated as per set industrial standards, these ANSI B 16.9 grade concentric reducers are dimensionally accurate and last for long duration. They are used to appropriately reduce into and out of circulating pumps. We also provide the clients customization facility to meet their specific needs.

TOSHWIN TUBES INDIA manufactures reducers (pipe fitting) to reduce the diameter of the suction piping to fit the pump intake, thus used to join two pipes of different sizes. Reducers are available in both eccentric and concentric designs. Concentric or eccentric reducers are used to properly reduce into and out of circulating pumps.




The various advantages include keeping big pipes and small pipes together as well as reducing noise and vibration at the same time. Our reducers are tested and verified for durability, accuracy and precision.
