100TONG KR-008 Threaded Concentric Reducer 3″ – 2″
Delivers uninterrupted, centered flow transitions with ductile iron strength and fast threaded assembly.
The 100TONG KR-008 Threaded Concentric Reducer 3″ – 2″ provides a reliable diameter transition for threaded piping systems. In addition, its concentric body keeps the flow path straight through the centre, which minimises pressure loss. Moreover, GGG 40.3 ductile iron maintains structural integrity even at extreme temperatures.
The reducer features a 3″ (DN80) large inlet and a 2″ (DN50) small outlet, both threaded to UNC / NPT standards. Its GGG 40.3 ductile iron body offers high mechanical strength and corrosion resistance, while the PN16 pressure class supports demanding lines. The working temperature range is -50°C to +150°C, and the concentric design keeps the flow line straight.
100TONG KR-008 Threaded Concentric Reducer — Technical Specifications
This reducer is widely used in fire-fighting systems and industrial process lines. Furthermore, it is preferred in HVAC cooling and heating circuits, especially at pump inlet and outlet connections. As a result, it maintains flow balance during diameter changes and extends system service life.
Key Advantages
