INFORMATION!
The O-rings require periodic inspection and replacement. As the interval depends on process-
specific variables, the length of the interval cannot be specified.
The O-rings are not part of the portfolio of KROHNE.
INFORMATION!
For 3A applications, O-rings must conform to the requirements of the 3A sanitary standard for
Flow meters, number 28-04 Class I or Class II (max. 8% milk fat).
The used O-rings must also withstand the processing, sterilization and chemical conditions for
the intended use ( for more information, contact the manufacturer)
