Quick-flange closures are used to close valves and pipelines with flanged ends without multi-fittings, nuts, blind flanges, gaskets and without additional tools.
The main components are made of aluminium and are very easy to handle due to their low dead weight. Sealing against the test piece sealing surface is achieved by an integrated O-ring. The construction absorbs the specified max. pressure load and keeps the connection between test specimen and flange seal tight via the self-locking spindle.
