K31 consists of three parts: a seal in PU (Polyurethane), an element made of NBR, and an anti-extrusion ring in POM. This seal is suitable for applications where high pressure is present. The anti-extrusion back-up ring in acetal resin guarantees better resistance to extrusion. The L profile of the sealing part in PU ensures furtherer protection against the entry of dirt particles.
