5.3 Resistance and permitted operating temperature of the sealing materials
The resistance and permitted operating temperature of the sealing materials
depend on the type and temperature of the medium conveyed. The exposure
time can adversely affect the service life of the seals. The sealing materials
comply with the regulations of FDA 21 CFR 177.2600 or FDA 21 CFR 177.1550.
The maximum operating temperature is defined by the sealing type and its
mechanical load.
