Abstract
A gasket includes a base extending circumferentially about a gasket axis, a central flange, a first arm, and a second arm. The first arm includes a first arm portion extending from the gasket base to a first radial axis and a second arm portion defining a first surface at a first angle and a second surface at a second angle, the second angle greater than the first angle. The second arm includes a third arm portion extending from the gasket base to a second radial axis that is perpendicular to the gasket axis and a fourth arm portion defining a third surface at a third angle and a fourth surface at a fourth angle, the fourth angle greater than the first angle, the fourth surface further from the third arm portion than the third surface.
