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.
