This modified face column accommodates virtually any profile thickness – essential in studying ‘self-sealing’ membranes and threaded fasteners. 

There are several ways to achieve this. The easiest consists of rigid plastic of desired thickness. An inch or two can accommodate almost any condition, including brick ties. Here, I’ve created a similar condition using layers. It’s easy, and columns are ready to fill in less than 24 hours. At just shy of one inch, it’s more than sufficient to study sealing interfaces at exposed threads under hydrostatic pressure. To also incorporate differential pressure, simply add an air-tight chamber and preferred negative draw.
