High Purity Concentric Reducer
The High Purity Concentric Reducer is a precision-engineered fitting designed to seamlessly transition between two different pipe diameters while maintaining a centralized flow path. Made from ultra-clean, contamination-free materials such as PVDF HP, PFA, PP-H, or High-Purity PE, this reducer ensures uninterrupted laminar flow in critical fluid handling systems.
It is widely used in semiconductor manufacturing, pharmaceuticals, biotechnology, food-grade processing, and ultrapure water (UPW) applications where absolute hygiene, low particle generation, and chemical resistance are essential. The concentric design eliminates turbulence and ensures consistent pressure distribution, making it ideal for maintaining system purity and mechanical integrity.
High Purity Concentric Reducer
- Smooth, centralized transition between differing pipe diameters.
