Straight reducer KF/NW 40–25 S/S – 30 mm
Stainless steel straight reduction ISO-KF 40–25, 30 mm length for connecting flanges of different sizes in vacuum systems. Compact design for connecting KF40 / NW40 with KF25 / NW25.



The straight reducer KF/NW 40–25 S/S is used to connect flanges of different sizes within the ISO-KF system. This version has a total length of 30 mm and represents a compact solution for the transition from a KF40 / NW40 flange to KF25 / NW25.
The reducer is made of stainless steel and is suitable for both laboratory and industrial vacuum applications.
The ISO-KF system design according to ISO 2861 / DIN 28403 allows for use with common KF components, such as clamps, centering rings with seals, blanking flanges, and other adapters.
The short construction length of 30 mm is particularly suitable for compact vacuum assemblies and applications with limited installation space.
