The Chesterton 20KD Face and Static Seal is a continuous compression seal design in static applications, and is often applied as an upgrade to conventional face seals or O-Rings. designs. The 20KD design provides excellent performance in static applications in hydraulic or pneumatic equipment including flange and valve control units.

The 20KD optimum design provides minimum seal deformation through a better fit in the seal cavity and excellent pressure distribution through the seal cross section, which is accomplished through better geometrical and dimensional stability (Figure 1 on the next page). 20K D-Rings can withstand higher operating pressures compared to conventional O-Rings.
