Product Overview
Flat flange vessels are large-volume reaction vessels consisting of a lower part and a lid. These two parts are held together by a clamping ring. The transparent O-ring made of silicone serves as a seal for flat flange vessels with an annular groove. It prevents tilting of the ground surfaces between the vessel and the lid. Chemical resistance is limited compared to FEP coated O-rings.
