5. Maintenance and Inspection
5.1 Cleaning and fitting
Usally no cleaning is necessary.
5.2 Inspection of the O-ring seal
The O-ring seal used in the wetted parts of the fitting is made of silicone rubber which has
superior resistance to corrosion and is suitable for use with most process liquids.
Usually no periodically inspection is necessary. To prevent trouble, replace the O-ring seal
periodically, e.g. every year.
Note:
For chemical resistance of the used material refer to General Specifications sheet
GS 12B06K02-01E-E.
