Design suggestion for a tight (in both way) and easy to open flange


I attached to this post a scheme of a suggestion for a very tight flange in both way (pressure inside or outside) and easy to open. The principle is to squeeze the joint by approaching both parts of the flange with a screwing system. I guess the scheme explain it better.

Nice idea. But may be complex for building.



McMaster-Carr has some really useful high-pressure washers that seal around the screw and the surface of the material. They are relatively cheap and super useful.

Food for thought.
