Delta Gaskets

Gaskets can be yielding or self-sealing or both. For example a delta gasket and Bridgman gasket are both... 

Delta Gaskets These are self seahng gaskets sealed by internal pressure. They do not require any initial seating or bolt stress. Good for pressures greater than 5,000 PSI.

From a design standpoint, the total hydrostatic end force, H, is taken by the threads in a threaded closure, or by the studs in other designs. Various types of gaskets can be used with either design but all are the self-sealing type such as Bridgman, delta or double cone. 

The individual design requirements for lens, delta, and double-cone gaskets are given in the next three sections.
