BLANK FLANGE KF/NW 40 S/S
The KF/NW 40 blanking flange is used for reliable sealing of open vacuum ports in systems operating with a standardised NW 40 connection. Thanks to its stainless steel construction, it provides high corrosion resistance and a long service life under demanding operating conditions.



The KF/NW 40 S/S blanking flange is designed for the temporary and permanent sealing of flange ports in vacuum systems. Made from 304 stainless steel (1.4301), it ensures high mechanical strength, corrosion resistance, and reliable function even under demanding operating conditions.
Thanks to precise workmanship and manufacture according to ISO 2861 and DIN 28403 standards, the flange provides a precise fit, high-quality sealing, and full compatibility with all common ISO-KF components.
Its application is wide-ranging – from laboratory lines and surface technologies (PVD, CVD), through the semiconductor industry, to industrial vacuum installations where firm, secure, and long-term system sealing is required.
