PPH Vitroling Reducer Coupler
A PPH Vitroling Reducer Coupler is a specialized pipe fitting made from Polypropylene Homopolymer (PPH) with an internal Vitroling (fluoropolymer such as PTFE/FEP/PFA) lining, used to connect two pipes of different diameters while providing enhanced chemical resistance and protection against corrosive fluids.The PPH Vitroling Reducer Coupler is a high-performance piping component designed to connect two pipes of different diameters while ensuring superior chemical resistance and mechanical integrity. Made from Polypropylene Homopolymer (PPH) with Vitroling lining (usually PTFE or fluoropolymer-based), this coupler is ideal for handling aggressive chemicals, high-purity media, and corrosive fluids.
It is widely used in chemical processing, pharmaceuticals, water treatment, and other industrial applications, where reliable sealing and resistance to chemical attack are essential. The internal lining ensures maximum compatibility with harsh media, while the PPH body provides structural strength.It is a reducer coupling with a protective inner lining that allows safe connection of different pipe sizes, especially in systems handling highly corrosive or high-purity fluids.
