100TONG KR-008 Threaded Concentric Reducer 4″ – 2″
Reliable diameter transition that keeps flow continuous in high-pressure lines.
100TONG KR-008 Threaded Concentric Reducer 4″ – 2″ provides a dependable diameter transition for threaded piping systems in high-pressure lines. In addition, its concentric design directs flow along the axis, which minimizes turbulence. Moreover, the GGG 40.3 ductile iron body offers high mechanical strength and impact resistance for demanding installations.
The reducer handles a pressure class of PN25 / 25 bar and operates between -50°C and +150°C. Its concentric flow character runs parallel to the axis, maintaining stable performance. The threaded connection type, furthermore, allows quick assembly and disassembly on site. It is manufactured to EN 558-1 and DIN 2353 standards, with a large diameter of 4″ (102 mm) and a small diameter of 2″ (51 mm).
