Back-up Rings in the Sealing World – Reliable Support for Your Sealing Systems

Back-up rings stabilize O-rings and prevent gap extrusion under high pressure. They extend the service life of seals and enhance operational reliability. They are particularly used in hydraulic and pneumatic systems to prevent deformation of seals. In the automotive industry, they are found in engines, transmissions, and braking systems, while in the chemical industry they demonstrate resistance to aggressive media. They are also in demand in medical technology due to their compliance with stringent hygiene standards.

The choice of the right material – whether PTFE, POM, NBR, FKM, or PEEK – determines resistance to pressure, temperature, and chemicals. Our high-quality back-up rings reduce leakage, minimize maintenance effort, and improve sealing performance.
