G-ST-P / ISO Gaskets

G-ST-P / ISO Gaskets made of electrically insulating materials

The G-ST-P/ISO is our specialist when it comes to preventing corrosion. When different flange materials are paired, for example steel flange and stainless steel flange, electrochemical corrosion can occur. To prevent the formation of a galvanic element, these materials must be electrically separated from each other.

The G-ST-P/ISO gasket set is used here. The design corresponds to our
G-ST-P/KN, but differs in the choice of materials. Instead of steel or stainless steel, electrically insulating materials such as PP/PE, UPGM 203 or EP GC 203 are used here, combined with a sealing lip made of one of our elastomers.

The gasket set also includes the screw bolt insulation. This is composed of an insulating hose consisting of coated glass fabric hose (Mylar/Glasseide) and insulating washers made of EP GC 203.
