5.3 Resistance of Sealing Materials
The resistance of sealing materials depends 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.
Resistance:
•
+ = good resistance
•
o = reduced resistance
•
- = no resistance
