Knife Edge Sealed Flange ( Ke-Flat Flange )
 
1-1/3" OD. Mini Flange
Ke-Flat Blank Flange
Ke-Flat Bored Flange
Our products utilizes unique engineering/manufacturing techniques to ensure leak free performance of Ke-Flat flanges. The reliable sealing performance of Ke-Flat flange is a result of the geometry design which captures the gasket material from cold flowing. When the conical sealing knife edge of the KE-Flat flange is pressed into the flat gasket, a cold flow of the gasket material occurs. The vertical flange wall lilits this cold flow.
 

Features

Identical mating flanges
Mate with all other Conflat Style flanges
Leak-tight even with minor nicks/scratches on gasket
Wider selection range of Tube Fittings
Components can be welded to flanges
