The special silicon grease for the lubrication of hot and cold water taps is especially suitable for drinking water taps. Thus, it is registered at NSF International for the application in drinking water systems (NSF/ANSI-Standard 61; Temperature: commercial temperature 82 °C). The use of this lubricant is physiologically inert. The tap grease is neutral in taste and odour, resistant to hot and cold water, neutral to beer froth, resistant to steam and disinfectant solutions. Moreover, it is neutral towards elastomers (NBR, EPDM etc.), except silicone gum.
