HECKER® Locking gasket AK 2650

Media:                 Water, vapour, hydrous acids, weak acids up to strong lyes, non aggressive vapours and gases.

Design:                Rolled out of a stainless steel reinforced ceramic fabric which is provided with a special elastomer coat on both sides. The gasket is graphitized on both sides.

Notes:                 AK 2650 has been developed e.g. for hand and manholes, covers, blast furnace flaps. The gasket is very smooth and elastic. It is well suited as an asbestos-free alternative to the proved AK-type 2039. Due to the graphitizing, adhesion of the gasket to the counter surface is nearly avoided.
