Flange gaskets for water supply

Flange gaskets for drinking water

Drinking water is our most valuable natural resource. Wherever drinking water is pumped and transferred, seals without harmful ingredients play a major role. Legislators therefore rightly place particularly high demands on flange gaskets that are installed in contact with drinking water. Gaskets installed in drinking water and service water supply systems are therefore tested by numerous release regulations.

Flange gaskets for water supply from Kroll & Ziller meet and even exceed the most stringent requirements. Our gaskets not only conform to the minimum standard, they go far beyond it. In this way, in addition to excellent quality management, we ensure that any process from water withdrawal and treatment to withdrawal by the end user can be carried out safely.

Flange gaskets with certifications according to W270 and elastomer guideline

Kroll & Ziller stands for certified quality. The flange gaskets for water supply in contact with drinking water have several certifications at once:


Hygienic harmlessness according to DVGW worksheet W270


DVGW type examination certification DIN EN 681-1


Confirmation of conformity according to elastomer guideline (successor to KTW)

We are the only manufacturer to offer a gasket in the material NBR-DUO-EL, which is suitable for use in contact with drinking water according to DIN EN 681-1, as well as for use in flange connections in supply lines and components for gas and liquid hydrocarbons according to DIN EN 682. This saves storage costs and prevents confusion.
