KB20A

The KB20A is a single acting / uni-directional seal used for both static and dynamic applications and is designed to be installed into common international sized O-Ring grooves.

Profile KB20A excels in both low and high-pressure applications while also having the ability to operate at both high and low temperatures and in a multitude of different media through the correct choice of material combination.

It provides superior resistance to extrusion through its specially designed active Back-Up rings. Under system pressure the seal flange lifts the Back-Up Rings to block the clearance gap, protecting the sealing bulb at all times.
