Static Sealing Elements
K801 Back-up Ring
K801 back-up rings are sealing elements that are generally used behind the o-ring in order to ensure system security and minimize extrusion gaps in many applications. Curved design of K801 provides optimum surface pressure distribution between the o-ring and the counter surface.
