Attention: Silicone parts do not require lubrication.  Do not grease them. Greasing silicone 
parts can change their molecular construction and cause premature degradation of the material. 

Attention: Do not use hydrochloric acid for cleaning parts. Hydrochloric acid, even when well 
diluted, attacks the coating of metal parts and leaves a corrosive deposit that damages plastic 
parts and O-rings.
